Sasha Stone was only four-years-old when her mother was attacked and strangled to death in October of 1981 in her home in Carmel by the Sea, California 鈥 a community known for its white sand beaches, surfing and vibrant arts community.

Growing up without her mom took its toll. Stone recalls having traumatic nightmares that started when she was five.

鈥淚 was Little Red Riding Hood鈥here was this terrifying wolf that was chasing after me that had 鈥illed my family鈥t was terrifying, and I would wake up screaming on a regular basis,鈥 she tells W5.

She was also angry. Angry about the lack of answers, about the fact her mother鈥檚 killer had never been caught. She made it her mission to make sure this case wouldn鈥檛 be forgotten.

While in her teens, she turned to detective Lins Dorman -- one of the original detectives on the case.

鈥淚 marched into Lins鈥 office鈥 and said 鈥榳hy haven鈥檛 you re-opened this?鈥欌

Her mother was Canadian Sonia Herok-Stone -- a 30-year-old enjoying a flourishing career with Levi-Strauss at the time of the murder.

And Det. Dorman was one of the first on the scene that day in 1981.

鈥淢y first impression was that I knew this person had struggled for her life鈥 her clothing was basically completely removed鈥.I couldn鈥檛 tell what was around her neck, but it turned out to be her pantyhose,鈥 he said.

Dorman encountered the man he believed to have killed Sonia -- Michael Glazebrook -- one day after the murder, while canvassing Sonia鈥檚 neighbourhood. He detailed his initial impressions of Glazebrook in this .

鈥淭he first thing I notice about him is that he鈥檚 extremely musclebound. He鈥檚 got a T-shirt that鈥檚 stretched so tight you can see every muscle in his back and his arms鈥 I鈥檓 immediately drawn to his right cheek,鈥 he said. 鈥淗e鈥檚 got this deep red scratch.鈥

During that initial meeting, Glazebrook -- a 25-year-old who recently moved into the area -- gave Dorman three different stories about his whereabouts the day of the murder, as well as how he got the scratch on his face.

鈥淗e told me the first story was he went over to his father鈥檚 house, and didn't mention anything about cutting himself,鈥 said Dorman. 鈥淭he second story was that he cut himself on the day she was murdered and went to the hospital and was kept overnight. And the third story was that he cut himself on the 16th.鈥

Dorman says Glazebrook also appeared to be on edge.

鈥淗e was fidgeting, he was hemming and hawing, his voice was stammering鈥 I鈥檓 thinking, boy, this guy is really nervous,鈥 he said. 鈥淭his could be our guy.鈥

Glazebrook鈥檚 trial lasted 18 days, and in a devastating blow, the judge ruled that none of Det. Dorman鈥檚 interrogation of Glazebrook could be presented to the jury because Glazebrook had been picked up on a traffic warrant, but questioned about a murder investigation.

Glazebrook鈥檚 1983 trial ended in a hung jury, but neither Dorman nor Stone ever gave up their search for answers. Long after retirement, Dorman continued to keep tabs on the case, often calling the sheriff鈥檚 office for information.

鈥淢y last day in the sheriff鈥檚 office was January of 1992 and they were still on my mind.鈥

CASE RE-OPENED

But in 2020, the Monterey County District Attorney鈥檚 office re-opened Sonia鈥檚 case and assigned Det. Arras Wilson to review it. Wilson spent time reviewing Dorman鈥檚 files and early on, reached out to him to discuss the case.

The new investigation led to a breakthrough and 67-year-old Glazebrook was ultimately convicted and sentenced for the murder of Herok-Stone.

While grateful the person who killed her mother is behind bars for life, Stone, now 46, has since channeled her energy into advocacy.

She fights for victims鈥 rights and restorative justice -- an approach that encourages offenders to take responsibility and recognize the harm they have caused, through discussions with the victim and community members.

鈥淲ork in restorative justice is having great success stories of people actually understanding the impact of what they did鈥 鈥榣et me make better choices鈥 so we鈥檙e not just releasing them back onto the streets and causing the same problem.鈥

Stone says the most effective approach is to attempt to stop criminals before any crime is committed.

鈥淚t鈥檚 actually paying attention to鈥 what鈥檚 going on with him? What鈥檚 happening to him? Before he even goes to the next step.鈥

In April 2023, Stone took the stage as the inspirational speaker for the ceremony in Salinas, Calif., where she spoke to a crowd of people and others who have lost loved ones to violence.

鈥淚 wish I could say that the impacts of trauma and violent crimes could be something we could just shake off鈥 but it takes so much more鈥 it takes building inner strength and stamina, human humility, compassion, grace, generosity, forgiveness,鈥 she told the crowd.

She paid special tribute to the person who continues to motivate her to do this work, her mother.

鈥淪he was a best friend to a group of Montreal adventurous kids who grew up together and eventually moved down to California to pursue their dreams,鈥 said Stone. 鈥淪he was a beautiful bride. She was a wife. She was a hardworking, business-minded, independent, talented young seamstress,鈥 said Stone. 鈥淪he was my mother.鈥

W5鈥檚 investigation, 鈥淲ho Killed Sonia,鈥 reveals why Glazebrook managed to roam free for decades and exposes what scientific evidence led to the eventual dramatic breakthrough in the case. Watch the episode for more.

Det. Dorman never got the chance to meet Sonia Herok-Stone, but finding the killer more than 40 years later still means the world to him.

鈥淗e took her life away, took away a mom, took away a sister. Took away a daughter. I know how I feel and I鈥檝e lost a loved one. It鈥檚 a horrible feeling because you鈥檒l never ever see them again. They鈥檒l never come back. And that鈥檚 how this case affects me.鈥
