The Costa Mesa (55) Freeway at Del Mar Avenue was shut down in both directions Wednesday when a woman dialed 911 to say she was armed and was holding up signs indicating her father was a serial killer, the California Highway Patrol reported.

The northbound and southbound lanes were shut down after the woman called authorities at 11:51 a.m., holding up signs indicating her father was the “I-45 Texas killer,” and reporting she was armed, CHP Officer Erin Winstead said.

The woman had parked her car in the center divider and had the sign on the back of the vehicle, Winstead said.

She surrendered about 1 p.m. without incident and the freeway was reopened, said CHP Officer Florentino Olivera.

The woman had a flare gun on her, Olivera said.

“She was telling the (CHP) she wanted her story to be told that her father was the Texas serial killer,” Olivera said.
