4:57 P.M., JAN. 22 UPDATE: The Thibodaux Police Department announced the arrest of the second suspect, who was still at large until apprehended by the Baton Rouge Police Department on Saturday afternoon.
Terrione R. Thomas will be transported back to Thibodaux for booking procedures.
He will be charged with second-degree murder.
As you recall, his brother, Timothy Thomas had already been arrested for accessory after the fact of second-degree murder.
Both arrests come after a shoot Friday evening at a private-event venue on St. Charles Street.
“It was an isolated event at this at this establishment,” said Lt. Clint Dempster, who serves as public information officer for the Thibodaux Police Department. “It was an argument that kind of broke out between two subjects who were there.”
Since 2018, there have only been eight homicides in the city, including these two, which is why police called the shooting abnormal.
“No, we haven’t had, you know, especially in the recent past, we haven’t really had a whole lot of calls at that establishment,” explained Lt. Dempster.
Seventy-year-old Lisa Johnson, also known as Lisa Miller, who a family member says suffered from dementia, was killed in the shooting. Alvin Turner was also killed. He was described as charitable and outgoing.
The family member says Terrione was Miller’s great nephew.
According to investigators. Terrione left the private party and then returned with a gun. He then allegedly shot Turner, and it is believed Miller may have been caught in the cross fire.
“We don’t know if she was just struck by gunfire during the incident,” said Dempster. “We have no reason to believe that she was a target at this point, but it’s still under investigation.”
