A Jefferson Parish grand jury has indicted 16-year-old Vincenzo “Jake” Randazzo as an adult on one count of first-degree murder and one count of attempted first-degree murder stemming from a July incident in which he is accused of attacking an elderly couple with a hammer in their home in Kenner.

Phillip Lynch Sr., 89, died about three weeks after the July 9 attack, which left his wife Anita with skull fractures.​

Randazzo was ordered held without bail Thursday. He is in the Jefferson Parish Juvenile Detention Center.

Randazzo lived in the same Woodlake subdivision as the Lynches and was someone they had grown to regard as a member of the family, a relative has said.

Their friendship began after Randazzo stole a gun from the Lynch home. After his father made him return the weapon, Randazzo agreed to perform odd jobs for the couple as a type of informal community service.

​Police said Randazzo became angry with his family after a shoplifting incident and went to the Lynchs' house asking for a ride to Baton Rouge. Phillip Lynch refused, and Randazzo grabbed a hammer and attacked them, stole the couple’s car and drove to Baton Rouge himself, police said.

He was arrested in Baton Rouge after crashing the car. Police said Randazzo confessed but claimed the frail Phillip Lynch had grabbed him.

The case was allotted to Judge Scott Schlegel of 24th Judicial District Court in Gretna.
