In an apparent case of mistaken identity, three teenagers opened fire on the car of a nine-months-pregnant Louisiana woman, killing both her and the child.

According to an arrest warrant obtained by ABC News, Kerisha Johnson, 36, was shot early on Sunday morning while attempting to pick up guests at a “teen party” in Baton Rouge. She was later discovered dead in her car.

Johnson’s childhood friend Deanna Williams told WBRZ, “It was just senseless.” She was a defenseless individual.

In a few days, Johnson was “due to give birth.”

Three 19-year-olds were detained by the police in connection with the shooting: Derrick Curry, Marques Porch, and Gregory Parker.

According to police, “several individuals” opened fire on Johnson’s white sedan as she was driving to the party. It appears that the shooters thought the car belonged to someone else.

A similar car had fired shots in the air while driving by the party earlier in the night, according to the warrant.

Johnson tried to flee but was fatally struck in the barrage.

The three men were photographed “raising firearms, pointing them at the victim’s vehicle and then firing” before leaving the scene, the warrant claims.

They admitted to police that they had been carrying a weapon when the shooting occurred.

“They all stated that they believed the white car was a vehicle from earlier in the night where [an] occupant had fired a round into the air as it drove past the teen party,” police wrote in the search warrant.

Porch told police that he provided Parker and Curry with guns before the shooting. While fleeing the scene, Porch was shot by an unknown shooter and sustained non-life-threatening injuries.

According to the Baton Rouge Police Department, the gunmen were each charged with first-degree feticide and second-degree murder.

During a court appearance on Monday, the three suspects were ordered held without bond, according to East Baton Rouge Parish Courthouse officials, who spoke to ABC News. According to jail records, they are being held at the East Baton Rouge Parish Prison.

From June to November 2022, Porch served as a corrections officer for the West Baton Rouge Sheriff’s Office. In February, he went back to working as a transportation driver part-time for the sheriff’s office.

After his arrest on Sunday, the sheriff’s office “immediately terminated” him, a spokesperson told ABC News.
