CASTRO VALLEY, Calif. -- Tuesday night, friends and relatives of the two teens killed in a Castro Valley accident possibly linked to street racing gathered to grieve and face the difficult task of trying to make sense of the horrific tragedy.

Just steps from the accident scene on Dublin Canyon Road, friends have created a memorial to remember the two friends.

18-year-old Clark Wright recently graduated from Castro Valley High School and 17-year-old Sarah Streicher was just weeks from starting her senior year at the school.

Tuesday night, one friend fondly recalled going with Clark on a church trip to help poor children in Mexico.

"He kind of shone. We'd go and play with the little kids. He would just light up. It was really cool to see," remembered Jill Eversole.

At around 12:45 a.m. Tuesday morning, the California Highway Patrol says Wright was speeding in his 1997 white Corvette with his friend Streicher riding alongside him.

He lost control of the car as they headed westbound on Dublin Canyon Road, hit a curb and left about 400 feet of skid marks before hitting a utility pole.

"After they left the roadway they took down a hundred feet of fence, they snapped right through the utility pole and still continued another 200 feet before coming to rest," explained CHP officer Steve Creel.

The teens died at the scene.

The CHP says there is no sign that drugs or alcohol were involved, but investigators say Wright had been drag racing shortly before the accident with an unidentified 18-year-old man in a BMW.

Right now, the CHP is trying to determine if Wright and the other driver were still racing when the corvette careened out of control.

Friends told KTVU Wright's car was his pride and joy.

"He was always talking about his car. 'What are you going to do? What are you going to put in it?' I like to fix mine up too," said Chris Garcia, a friend who worked with both Wright and Streicher at the Castro Valley P & W Market.

Garcia says he saw them at work just hours before the accident.

"They're good people. Everybody's going to miss them," said Garcia.

Castro Valley High principal Pete Alvarez told KTVU the school will offer students grief counseling starting Wednesday, even though classes don't start for two weeks.

"I'm deeply upset by this. I want to make sure that my students make it thru this," said Alvarez.

A two mile stretch of Dublin Canyon Road was closed to traffic Tuesday as PG&E crews worked to replace the downed power pole and damaged lines.

There's no word yet on a memorial service for the two teens.
