Investigators recovered a weapon that could have been used to kill a 5-year-old Houston boy whose body was believed to have been kept in a storage unit before being discovered at a motel in East Texas.
The weapon was being tested to see if it was the one used to kill Samuel Olson, Andrea Beall, a district attorney for the Harris County District Attorney’s Office, told reporters Thursday.
“We’re not going to stop until we get justice for little Samuel,” said Beall, who declined to say what type of weapon was found or used to kill the boy.
The disclosure came the same day a third person was charged in the case. All three face charges of tampering with evidence and none have been charged with murder, although prosecutors said earlier this month they expected to lay additional charges against the one of them, Theresa Balboa, who was Samuel’s father’s girlfriend.
Samuel’s cause of death was ruled a homicide, but authorities did not say how he was killed.
A Jasper County grand jury indicted 27-year-old Dylan Walker on Thursday. Court records did not mention a lawyer who could speak on his behalf. Balboa and his roommate, Benjamin Rivera, had already been charged.
Authorities allege that on June 1, Walker helped Balboa move Samuel’s body from a suburban Houston storage unit to a motel in Jasper, about 135 miles (215 kilometers) northeast, where he was found inside a plastic tote in a room Walker had rented for Balboa.
Police believe Samuel, who would have turned 6 on May 29, died weeks before Balboa reported missing on May 27, according to an arrest affidavit. His body was kept in a tub in Balboa and Rivera’s suburban Houston apartment until they put it in the tote and hide it in a storage unit on May 13, according to police.
After Walker helped Balboa move the body to Jasper, he called authorities to let them know his whereabouts, police said. Prosecutors said Balboa was on her way to Louisiana when she was arrested in Jasper.
Balboa, 29, remains jailed for bonds totaling $ 600,000. Rivera, 27, and Walker were released after posting bail.
“I am grateful that justice is starting to be served,” Sarah Olson, Samuel’s mother, said in a statement.
Samuel’s parents had been involved in a bitter custody battle since filing for divorce in January 2020. His mother had primary custody, but she had not seen her son since the summer of 2020, according to her lawyers.
Samuel had been living with Balboa since April 30, the last day he was seen at school. Authorities did not say why Samuel stayed with Balboa instead of his parents.
