The search continued Saturday for Ronald Green Sr., who authorities believe jumped from a Mississippi River bridge after killing his wife and 12-year-old son at their home in Gonzales on Thursday.

“There’s obviously a possibility that he didn’t jump, but it’s very slim,” Lt. Col. Bobby Webre, of the Ascension Parish Sheriff’s Office, said Friday.

The East Baton Rouge Sheriff’s Office notified Ascension Parish deputies shortly after 2 a.m. Thursday that someone had called to report that Green told her he killed his family and was going to jump from a bridge, according to the Ascension Parish Sheriff’s Office.

Ascension Parish deputies found the front door glass shattered at the Green home on Lakeway Cove Avenue and Dewona Green, 40, and Ronald Green Jr., 12, shot dead in a bedroom.

Green Sr.’s car was found abandoned and still running on top of the Veterans Memorial Bridge in St. John Parish shortly after the discovery of the bodies of his wife and son.

Webre said Friday the St. John the Baptist Sheriff’s Office keeps boats manned by deputies on the river at all times because of heavy river traffic and is searching for Green’s body.

The St. John Sheriff’s Office also has alerted commercial boat traffic in the area for the possibility of a body in the water, Webre said.

“There’s no indication that he didn’t jump,” Webre said.

The Ascension Parish Sheriff’s Office is in possession of both of the vehicles that Green was known to drive, Webre said.

The Sheriff’s Office also sent out alerts for Green on state and national law enforcement databases.

Ascension Parish sheriff’s Chief Deputy Tony Bacala has said the search for Green’s body could take days, weeks or months.

Court records show that Dewona Wright Green filed for divorce Tuesday and previously filed three petitions for a protective order against her husband, citing extreme control issues and physical abuse.
