Balboa, 27, told officers the child’s mother and another man, dressed as a police officer, had picked up the boy around 7 a.m. that day. Houston Police investigators later said Samuel's mother was actually at her own home the morning of May 27, and said Balboa had been giving inconsistent statements.
On May 31, police searched Balboa’s apartment in Webster, a city within the Houston metropolitan area, and towed her car.
On June 1, Jasper Police investigated a Crime Stoppers tip at the Best Western Inn on West Gibson Street in Jasper, about 150 miles northeast of Houston, where they found Balboa. Then officers found a boy’s body in room 106.
Officers smelled "possible decomposing human remains,” according to Balboa’s probable cause affidavit. The officer found a tote bag with a yellow lid that was zip-tied. When he opened the lid, the officer "observed what appeared to be a child's body wrapped in a black plastic bag laying inside the tote."
Rivera and Balboa allegedly placed Olson's body in a bathtub for two days, then into a plastic tote and plastic kept in a storage unit, until the body was finally found at the motel with Balboa.
Balboa and Rivera were recording on Walmart surveillance video buying duct tape and a plastic container, KPRC reports.
Ben Rivera appeared in court on June 24, and was later released on $100,000 bond but was ordered to held under house arrest, and was banned from the use of firearms, as well as being in contact or around children and family members of Balboa or Olson, according to KTRK.
Prosecutors said Rivera was cooperating with homicide investigators.
Another man, Dylan Walker, has also been charged with tampering with evidence, KPRC reports. Court documents say Walker drove Balboa to Jasper and rented the motel room.
