Thomas Snow is also charged with a gas station robbery the day before his parents, Clifford and Joyce Snow, 68 and 66 respectively, were found dead.
He also allegedly fled from Minnesota police in the days following the discovery of the bodies. He has yet to be charged and is awaiting extradition from Minnesota to Indiana. Police say he is not cooperating with the investigation.
The bodies were found Friday around 4:30 p.m. after their daughter, who lives out of state, asked police to make a well-being check.
Police say Thomas Snow has a criminal record that includes drug charges. There was also an active warrant for his arrest for fleeing Indiana police. A motive for the killings is still unknown.
The coroner says the bodies were in an advanced state of decomposition when they were found. Dental records and DNA were used to identify the victims. Both suffered blunt force trauma. Joyce Snow also suffered strangulation. The time of death is unclear pending test results.
Neighbors in the small town were stunned as police investigate exactly what happened. On Saturday afternoon, a steady stream of the curious passed by the home located near the intersection of 197th and Calumet avenues, where two people were found dead the previous day.
"You don't expect this to happen in a small town like this, and you hear about it and wonder what else is going on," said neighborhood resident Hannah Wielgos. "Why would someone do this?"
"Just a bunch of cop cars," said neighborhood resident Jacob Rothrock. "I didn't know what was going on, and I didn't ask."
