BILLINGS - Billings police said Friday officers have detained one 19-year-old "person of interest" in connection with the homicide of a missing 12-year-old boy and arrested another 13-year-old on suspicion of tampering with evidence.

Lt. Matt Lennick said in a news release police recovered the body of Andy Paul Beartusk Martinez in an outbuilding after obtaining a search warrant for a residence on the 900 block of Terry Avenue. While Lennick did not identify Martinez in the release, family members confirmed the identity to Q2 News.

Martinez was reported missing March 7, and police followed up leads in Billings and Pryor, according to Lennick. Family members also took up the search in the area around Central Park, where he was last seen.

The 19-year-old was detained, according to Lennick, but he has not been charged. The 13-year-old was charged and taken into custody of Youth Services.

Billings police and the Bureau of Indian Affairs are investigating.

Family of the 12-year-old says Beartusk Martinez was visiting Billings from California when he disappeared and claims he had gotten involved in gang activity. Billings police also say the group of teens the 12-year-old was known to associate with were well known to officers.

Family says they choose to remember the other side of Andy Beartusk Martinez. His cousin, Ava Rodriguez, says she’ll forever remember her cousin as a happy 12-year-old boy.

“He really had a lot of joy. He was always smiling. He kept his feelings inside mostly, but showed joy outwardly,” she said.
