A Sacramento man has been convicted of felony charges of making criminal threats and burglarizing his parents’ home, as well as a misdemeanor charge of elder abuse.

A Sacramento County jury Thursday also found that 42-year-old Elon Green Jr. had previously served time in prison for being a felon in possession of a firearm.

On Sept. 2, Green approached his parents’ house. When he saw his stepmother in the garage, he rushed toward her and repeatedly threatened to kill her, according to a Sacramento County District Attorney’s Office news release. She retreated into the house, locked the doors and called 911.

Authorities said Green then entered the attached garage and attempted to break through the interior door with a screwdriver. His 86-year-old father, who uses a wheelchair, tried to stop Green’s attack, and Green responded by assaulting his father, prosecutors said.

Green’s criminal history includes four separate prior felony convictions for being a felon in possession of a firearm, a misdemeanor high-speed evasion from law enforcement, and several drug and alcohol-related charges. He has been sentenced to prison on two previous occasions, the District Attorney’s Office reported.

Green is to be sentenced Jan. 23 before Sacramento Superior Court Judge Greta Curtis Fall.
