Lisa then explained that a producer was interested in Lois’ story, with Carpenter not having been covered in a film yet.

The Trailside Killer was convicted of seven murders and confirmed responsible for an eighth, but cops suspect he could have killed two more.

Lois - who sadly died in 2021 - was Carpenter’s first known attempted murder, for which he spent seven years behind bars. star Lisa described: “She worked with him. He stuttered, so she felt sorry for him but was always nice to him.

“Here’s what happened. She was at the bus stop. They lived in San Francisco. She didn’t have a car so she took the bus, and she was going to the dentist in the morning, maybe before work. David Carpenter drives up and says, ‘Hi, Lois, can I give you a ride? I’d love for you to come see my new baby.’ He had a baby. He was married!”

Lois is said to have tried to turn the ride down, but Carpenter was adamant. “They start driving, and all of a sudden, she’s starting to feel , of course, because it didn’t feel right, and all of a sudden, he’s talking to her and he’s not stuttering. That’s when she knew,” Lisa said.

In a terrifying turn, Lisa recounted: “And she said, ‘David, what’s going on?’ He said, ‘I don’t know, Lois. Sometimes, something funny comes over me.’ And she knew she was f***ing cooked.”

Carpenter then started attacking Lois with a hammer, but in a life-saving turn, a military policeman was walking on the road she was being attacked on, and “shoots David Carpenter in the stomach.”

Lisa then described how her mum acted after the vicious attack. “This is the creepiest, weirdest part of it all. [Lois is] in full-on shock. He hit her at least five times on the head with a hammer. Her fingers are dangling. Her purse spills out, she opens the car door somehow, her purse spills out and she’s so busy picking up the items to put back in her purse. Her head is, like, gushing blood. She’s totally in shock, but all she wants to do is put her things back into her purse.”

Lisa added that she herself went to support her mum in court when Carpenter was facing the death penalty. Lisa was just 21 when Lois gave her testimony, and Carpenter was placed on death row - but in 2019 had his sentence changed to life without parole when .
