The wife of Weezer bassist Scott Shriner was hit with felony gun charges Tuesday … but, she seems to have caught a break — because she was facing a far more serious allegation.

Los Angeles County District Attorney Nathan Hochman formally charged Jillian Lauren Shriner with felony discharge of a firearm with gross negligence, and felony assault with a semiautomatic firearm. Jillian was originally booked on suspicion of attempted murder of a peace officer in the April incident.

As we first reported … Shriner was shot in the shoulder by police officers after allegedly pointing and firing at them on April 8 — cops were searching her neighborhood for a suspect in an unrelated crime when she came out of her house with a pistol in her hand to investigate.

Body cam and security footage show officers behind a wooden fence in a neighboring yard yelling at her to drop the gun … she then appears to raise her arm and fire, prompting officers to shoot back.

Prosecutors claim the alleged assault was “upon one of a group of three individuals standing behind a fence in the backyard of an adjacent property” in the Eagle Rock neighborhood of L.A. on April 8.

After she was struck, Shriner walked back inside her house. A woman who works for her called police from the house, and from the released recording of the call, it appeared Shriner didn’t realize she had confronted police officers … the call seemed to be about reporting a prowler in the neighborhood.

Shriner and the woman surrendered to officers outside the house within an hour. Shriner was treated at a hospital, then arrested on suspicion of attempted murder of a peace officer. She was later released on $1 million bond.

Prosecutors are seeking up to 19 years in prison if she’s convicted.
