Woman Arrested, Accused In Crash That Killed Bicyclist

Julianne Thomson Suspected In DUI-Related Crash That Killed Arthur John Jacbos

A young woman was jailed Thursday on suspicion of manslaughter, drunken driving and hit-and-run in the death of a 64-year-old cyclist in Carlsbad.

Arthur John Jacobs of Vista was fatally struck while riding his bike around 9:45 p.m. Wednesday, near the intersection of El Camino Real and Cassia Street, according to the county Medical Examiner's Office.

Emergency personnel found Jacobs, who was pronounced dead at the scene, the Medical Examiner's Office said.

Autumn Colley, who lives in an apartment across from the crash scene, said she rushed to her balcony when she heard a loud crash. When she looked out, she saw a white truck make a wide turn into oncoming traffic on Cassia Road and hitting a light pole.

Colley said the truck, which was going an estimated 50 mph, turned into the Villa Loma apartment complex. Colley ran to the complex where she said she saw police make the arrest.

Police found the unoccupied vehicle and, some time later, its suspected driver, Julianne Elyse Thomson, who was hiding in some bushes, Mendes said.

"They found her in the bushes," Colley told 10News reporter Allison Ash. "She was crying, hysterical, and she looked really young."

Thomson was arrested on suspicion of vehicular manslaughter, felony hit and run and drunken driving, he said.

It wasn't until after the arrest that Colley saw Jacobs' body on the ground, some 40 feet from his crumpled bike.

"And he was right there and, you know, it was horrible. It was just so sad," said Colley.

When Colley learned the driver had been booked on suspicion of DUI, she said, "It's just sick. When are people going to learn?"
