“We were able to link him to this crime through a friend and associate of his,” said Broadwater. “According to the associate and friend, stated that the defendant related to him that he shot the victim twice in the head.”

Masi’s murder happened Saturday, the case breaking open when investigators say they got a look at videotape from a gas station.

“The video showed the defendant and the victim were together, arrived together in the same vehicle,” said Broadwater.

State police say the victim and suspect knew each other, but they’re not sure to what extent.

The investigation also led to Thomas’ younger brother, Christopher Thomas.

According to court documents, Christopher Thomas buried the murder weapon in the nearby woods.

“He helped build an alibi for the defendant and filed a false police report when they questioned him,” said Broadwater.
