The bones and teeth of three children were found in September in a shed near a Missoula home.
Officials believe the bones - found September 27 at a rental house in Missoula - are from three children who were between 2 and 4, 5 and 8, and 6 and 10 at the time of their deaths, according to a search warrant application filed in Montana's Missoula County.
Andrew, Alexander and Tanner Skelton were 9, 7 and 5 years old when they last were seen the day after Thanksgiving in 2010.
ABC FOX Montana's Angela Marshall spoke on Thursday with a reporter at 13ABC Action News, WTVG.
Since, their disappearance has been investigated as a homicide.
"There has been nothing previously reported to police linking the brothers to Montana, and it is not known at this time if the remains are from related siblings", state police said in a statement.
Police in MI are working with law enforcement in Missoula, Montana to determine whether a box containing the remains of three children found at a home there in September could be connected to the Skelton brothers, who went missing in 2010.
