A Minnesota man whose 16-year-old son was found dead last month was charged with his murder on Wednesday.

According to KSTP, a preliminary autopsy report — which listed Jordan Collins Jr.’s death as a homicide — also stated he was possibly decapitated with a knife. The teen vanished on May 8 while staying in Columbia Heights with his father, Jordan Collins Sr., 38, who is believed to have killed him and discarded his body in a dumpster.

Collins Sr. was arrested on Monday, more than a week after his son’s body was discovered at the Elk River Landfill. Video footage from May 13 — five days after his reported disappearance — suggested his body was put in a Columbia Heights dumpster before ending up in a garbage truck.

Three days after Collins Jr.’s disappearance, police reportedly searched his father’s home and discovered various butcher and hunting knives in a bedroom closet. They also found possible blood in garbage cans, and carpet and a mattress that both had pieces missing from them, according to KSTP.

Blood found on items recovered from the home allegedly matched Collins Jr.’s DNA, leading police to conduct another search at the residence. This time, police found blood on a bedroom wall which also belonged to Collins Jr., KSTP reported.

Collins Sr. claimed he last saw his son on May 10. Phone data indicated he called his son for 20 seconds on May 13, a day after police informed him of his disappearance.

Collins Sr. is charged with second-degree murder. His bail was set at $2 million with conditions, including surrendering his passport and being prohibited from leaving the state. Without conditions, his bail is set at $3 million.
