Olson was reported missing from Houston on May 27. A few days later, a tip led authorities to a motel room in Jasper where Olson’s body was found.

According to an arrest affidavit, Olson may have died weeks before he was reported missing.

Court documents state that the boy’s father told authorities that Olson was at Balboa’s apartment from April 30 until the day he was reported missing. Balboa is Olson’s father’s girlfriend.

According to the court documents, Balboa's roommate told authorities Balboa called him on May 10 and informed him about Olson’s death.

Balboa’s bond was set at $500,000, but an additional $100,000 was added on for a previous charge.
