UPDATE AUGUST 22, 2019 (VIDEO ABOVE OF CASO DISPATCH CALLS)
Lenk and Colborn, as well as others, are by the red trailer at Josh Radandt's deer camp on November 7, 2005: "Is there anyone available to bring us down a roll of barrier tape needed down by the red trailer? We're gonna need an investigator to take a look at something. We've got a burning barrel just off the property. In the debris is a cell phone. Go just down the lane where the trailers are, that's where we are, west of the command post (on Avery Road)."

The image above is from November 8th, the day bones were found in or near Avery's fire pit. There are tire tracks from the field road to the fire pit. The field road connects the Avery property to the cul-de-sac on Kuss Road and the driveway to Radandt's deer camp and his quarry.
The image above is from a flyover on the morning of November 4th by NBC26: there aren't any tire tracks from the field road to Avery's fire pit.
UPDATE JUNE 13, 2017: Regarding the burn barrels, Zellner wrote on page 76 (footnote 8) of her motion filed on June 7, 2017 (page 92 of the PDF):
Bone fragments could not have actually been located in burn barrel no. two because this barrel had already been sifted by WSCL personnel on November 7, and no human bone fragments were discovered in this barrel or any of the barrels examined at that time. During their examination of barrel no. two on November 7, 2005, WSCL personnel used the same sifting apparatus that they later used to sift the burn pit behind Mr. Avery's garage. Suspiciously, the pieces of burned bone that were eventually found in barrel no. two were noticeably larger than the bone fragments from the burn pit. If bone fragments had been in burn barrel no. two when it was examined by Mr. Ertl and his team from the WSCL on November 7, 2005, the bone fragments would have been isolated by their sifting apparatus.ORIGINAL POST, PUBLISHED ON DECEMBER 14, 2016
The only barrels described as 55-gallon drums came from Radandt's deer camp. Three other barrels were described as "two metal barrels" and "a 50-gallon burn barrel" collected from Janda's backyard.
One of the three deer camp barrels, barrel #2, contained burnt bone fragments (CASO page 248).
Kratz swapped out one of Barb Janda's burn barrels and replaced it with "deer camp burn barrel #2." Or, if there were only three barrels, not four, as Bobby Dassey testified, Kratz shuffled the barrels by adding deer camp burn barrel #2 (or the contents there of) to the three barrels in Janda's backyard.
Kratz relabelled deer camp burn barrel #2 as Janda burn barrel #2 (he added a fourth barrel or he removed a barrel, returned a different barrel in its place, deer camp barrel #2, then recollected that substituted barrel and labelled it as Janda burn barrel #2).
When questioned at Avery's trial about cadaver dogs, Tom Fassbender testified that on November 5th, 6th, and the 7th, during evidence collection, a dog did not alert on the the fire pit behind Mr. Avery's garage, but a dog or dogs did alert on an area at or around the cul-de-sac on Kuss Road (GPS coordinates for this area are N44° 15.263 W87° 42.031, per CASO page 137).
At some point early in the investigation, "deer camp burn barrel #2"became "Janda burn barrel #2."
According to a friend of Joshua Radandt's who was at the deer camp between November 4-6, 2005, the woods and gravel pit at Radandt's quarry were searched the morning of November 5th, before Teresa's RAV4 was found at Avery Salvage Yard, but the deer camp wasn't searched prior to November 7th. They found human bones in and near Avery's fire pit (also referred to as a "burn pit") on the afternoon of November 8th (page 157).
"I was at the deer camp [at Radandt's quarry] when the car [Teresa's RAV4] was found about 300 yards away [on Saturday, November 5, 2005, by the pond in the "pit" of Avery Salvage Yard]. I didn't see anyone search the deer camp while I was there November 4-6th. They did walk through the woods and gravel pits that Saturday prior to finding the car. It [the deer camp] might have been searched by police between October 31st and when the car was found and after I was gone for the weekend. Don't remember. The reason Josh and Travis were on the sign up sheet that day [Saturday, November 5th] was because they were asked to give a statement regarding the fire. I have read about Josh being questioned at the deer camp, but it's not true. What some of you guys are missing since you haven't been to the deer camp is that the camp is at the same elevation as the Avery property where [Joshua claims] the fire was burning. The land between the deer camp and the fire is dug out. I could see Avery's shack/yard from the parking area of the deer camp. It isn't unreasonable to see a fire at dusk from that distance and sight line." - InTheKnow2016, August 30, 2016, RedditThe following outlines how "deer camp burn barrel #2" became "Janda burn barrel #2."
The barrel with the tag in the photo above does not look like the other barrels, and it appears to have letters stamped on the side. This barrel is newer and in better condition than Avery's barrel and the Janda barrels in the photos below. Is this barrel from Radandt's deer camp? "On 11/12/05, Property Tag #7958, burnt material with the words deer camp burn barrel printed on the container, was turned over to Riemer" (CASO page 248). Did Barb Janda have three or four barrels (pictured below)?
Above is evidence photo 52, the burn barrels from Barb Janda's backyard. There could have been only three, not four barrels.
Steven Avery told Detective O'Neill that Barb Janda had three or four barrels.
Barb Janda was interviewed on November 9, 2005, after Steven was arrested at his brother Earl's house in Whitelaw, WI. She was asked how many burn barrels she has in her back yard: she answered two or three (Barb also was asked how many burn barrels does Steve have, and she answered, "by the field is the only one I know of").
During direct examination, Bobby Dassey told Ken Kratz that there were three barrels (day 3, page 64), which should have been addressed by the defense but wasn't (Kratz simply responded, "Okay," and moved on):
Q. The next exhibit is Exhibit 52. Telt us what that is please?
A. That would be a picture of our burning barrels.
Q. What do you mean "our burning barrels'?
A. My mom's burning barrels.
Q. How many were there?
A. Three.
Q. Are you sure?
A. I don't know. I thought there was three.
Q. Okay. Where were the burn barrel's located?
A. In our back yard, right behind our garage
On Blaine Dassey's map, it shows there were may have been three, not four barrels (Skorlinski wrote a report on his and Wendy Baldwins's contact with Blaine at Cedar Ridge Restaurant in Maribel on November 5th; however, this report was not entered into evidence at Avery's trial). The following map of the property must have been drawn by Blaine during his interview on November 5th, although it was included in the DCI report of his second interview on November 7th (and the date of the map was changed).

Burn barrel from Avery's front yard
To summarize:
- On 11/11/05, DCI Agents Rindt and Pevytoe came to the Calumet County Sheriff's Department to go through five barrels.
- On the same day, 11/11/05, Property Tag #7947, burnt material, was found south of Avery's fire pit.
- On 11/12/05, Property Tag #7958, "burnt material with the words deer camp burn barrel printed on the container," and Property Tag #7963, "burnt material from the deer camp," were turned over to Riemer.
- Three burn barrels that were taken from the deer camp were processed on 11/12/05, per Pevytoe's testimony, direct exam, day 18, page 34.
- On 11/12/05, Riemer, Pevytoe and Ebben processed item #643, along with #642, #644 and #645 (CASO, page 248). Items #642, 643 and 644 were 55-gallon barrels with miscellaneous items inside (the three deer camp burn barrels). When processing Item #643 they found various bone fragments.
- Riemer wrote in the report that material in a burn barrel from Radandt's deer camp included a burnt bone and possible tissue pieces. The burnt bone from the deer camp burn barrel was labelled Property Tag #7963, "burnt bone pieces from Barrel #2."
- Riemer, in his 11/12/05 report, also referred to the deer camp burn barrel, Item #643, as burn barrel #2 (CASO page 248).
- The burnt material found in the deer camp burn barrel was labelled with Property Tag Nos. 7958 and 7963.
- However, Hawkins wrote that Remiker and Dedering found the bone fragments when they sifted Property Tag #7963 on 4/11/06. They
claim to have collected the bone fragments and labelled them Item #21,
Property Tag #7429, but this number is out of sequence and should have
been assigned earlier than #7963, which was processed on 11/12/05. The report below has Riemer listed as the author, but it appears to have been written first by Riemer and then added onto by Hawkins (pages 729-733).We began again on 04/11/06 at 0829 hours. The personnel available on 04/11/06 were Deputy JEREMY HAWKINS of the CALUMET COUNTY SHERIFF'S DEPARTMENT, Special Agent KEVIN HEIMERL, Det. DAVE REMIKER of the MANITOWOC COUNTY CALUMET COUNTY SHERIFF'S DEPARTMENT, Sgt. BILL TYSON, Inv. JOHN DEDERING and me (Deputy RIEMER) of the CALUMET COUNTY SHERIFF'S DEPARTMENT.
At 1108 hours, Inv. DEDERING and Det. REMIKER began processing Item #7963.THE BURN BARRELS AND AVERY'S FIRE PIT
At 1050 hours, Special Agent FASSBENDER checked out and checked in at 1117 hours along with Inv. DEDERING, Det. REMIKER and Inv. WIEGERT.
At 1157 hours, Item #7954 began to be processed by Det. REMIKER.
At 1157 hours, Item #7958 was processed by Deputy HAWKINS and me.
Item #21, Property Tag #7429, bone fragments from sifting of Item #7963, collected at 1140 hours on 04/11/06.
At 1157 hours, Deputy RIEMER and I processed Property Tag #7958, a five gallon pail of debris. When the five gallon pail was finished being sifted through, the contents were placed back into the five gallon pail and then resealed.
At approximately 1230 hours, Deputy RIEMER and I processed Property Tag #8650, debris pile matter in a five gallon pail. All possible bone fragments were taken out of the debris pile and placed into a cardboard pill box. When the five gallon pail was done being sifted through, the possible bones were packaged in the cardboard pill box by Deputy RIEMER. The sifted material was placed back into the five gallon pail where it was then secured.
Once all the pails were sifted through, Deputy RIEMER released the following items back to me:
Property Tag #643, a 55 gallon barrel with miscellaneous items inside
Property Tag #642, a 55 gallon barrel with miscellaneous items inside
Property Tag #644, a 55 gallon barrel with miscellaneous items inside
Property Tag #1102, a 50 gallon burn barrel, one-quarter full of material
Property Tag #7921, a metal barrel with burnt material
Property Tag #7922, a metal barrel with burnt material; the barrel has the number 4 on it

Property Tag #7948, burnt material
Property Tag #7958, burnt material, deer camp burn barrel
Property Tag #7963, burnt material
Deputy RIEMER also turned custody of the following items over to me:
Property Tag #7429, bone fragments from Item #7963
Three 55-gallon burn barrels were collected from Radandt's deer camp, but there isn't a report by CASO or MTSO that explains when and how that happened.
One of the three deer camp barrels, barrel #2, contained burnt bone fragments (CASO page 248).
Barrel #2, the one with the bones that was collected from the deer camp, became "Janda's Burn Barrel #2." Kratz swapped and relabelled the barrels.
