REDDING, Calif. -

23-year-old Teddy Robertson of Redding, is behind bars after he turned himself in at the Shasta County Jail Friday less than 24 hours after a warrant was issued for his arrest.

Robertson is accused of throwing a coffee mug during a fit of road rage at Redding grandmother Joann Lambrecht-Vester, sending her into a coma for nearly two weeks.

“I'm happy, I'm happy that, you know, we can have closure a little bit now. I know who did it,” said Joann’s daughter Mollie Aitken.

Aitken said when she first got the call her mother’s alleged attacker was in custody, she was nervous.

“I don't know why I got really nervous. But then I felt really relieved,” Aitken explained.

The road rage incident happened April 1 on Cypress Avenue just off Interstate 5.
Joann was sitting in the passenger seat of a car being driven by her husband. Her husband accidentally cut off Robertson, who became enraged over the incident.

Police investigators said Robertson tailed Joann and her husband, then chucked a coffee mug at her face, splitting her nose – causing it to bleed profusely.

Joann had just gone through open heart surgery weeks prior to the attack and was on blood thinners. Because of the violent attack and mix of medications, Joann had a heart attack.

“I'd ask him why he would think it's OK to throw a cup at her. Especially if she was just trying to diffuse it,” Aitken said with a bit of anger.

“I want to know if he feels guilty or if he's just blowing it off like 'I did what I did but crud, now I'm in jail,’” questioned Aitken.

Redding Police investigators used tips from the public and fingerprint evidence left on the mug to connect Robertson to the crime.

"Fortunately with a lot of help from the community, a lot of tips, we eventually came across a tip that was very valuable,” explained Sgt. Shawn McGinnis with the Redding Police Investigations division.

"The more we investigated that tip the better it looked. And we discovered this individual that we were looking at actually had a vehicle that matched the description. The vehicle appeared to go into hiding, we couldn't find it after awhile which caused more suspicion to fall upon that person,” said McGinnis.

Robertson was charged with four felonies; assault with a deadly weapon, battery with serious bodily injury, throwing an object at a passenger of a vehicle with intent to injure, and elder abuse.

Robertson is now being held at the Shasta County Jail on $100,000 bail.

The vehicle Robertson is suspected of driving that day has not yet been located. It is described as a 2002 dark green Nissan Xterra bearing California license plates 4PJJ504.

Anyone with information on the whereabouts of the Xterra, or further information regarding Teddy Robertson or the circumstances of this case, is asked to contact Shasta County Secret Witness at (530)243-2319 or Redding Police Department Investigations at (530)225-4214.
