BURLINGAME -- Video from a red-light camera has led to the arrest of an 18-year-old man in connection with a fatal shooting on U.S. Highway 101 in Burlingame in late September.

Doyal Malcolm Webber is in custody without bail in San Mateo County Jail after his arrest Wednesday afternoon in Hayward for the murder of Londell Wilson, 25, of San Mateo, Burlingame police reported.

Wilson was shot once in the upper torso while driving northbound on U.S. Highway 101 north of the Broadway overpass at about 10:30 p.m. on Sept. 30. His silver 1990 Honda Accord then crashed and landed in a ditch at the side of the highway. He was pronounced dead at San Francisco General Hospital shortly thereafter.

An eyewitness described three vehicles near Wilson's car that appeared to be involved in the shooting, Burlingame police reported.

An unexpectedly quick return on video footage of two of the suspect vehicles, which police released publicly on Tuesday, resulted in Webber's arrest at 5:45 p.m. the next day, according to Burlingame police Cmdr. Mike Matteucci.

The video was taken about a minute after the reported shooting, from a Millbrae red-light camera system at the intersection of Millbrae Avenue and Rollins Road, just off the next northbound exit from the highway.

On Wednesday, a private citizen came forward to police saying he had seen media reports and recognized one of the vehicles, a turquoise 1980 Oldsmobile station wagon, which he had seen in his neighborhood, according to Matteucci.

Police soon found the station wagon, as well as the other two vehicles, a burgundy 1978 Chevy Caprise, and a white 1970 Buick Skylark, Matteucci said.

Subsequent interviews with witnesses identified Webber, a passenger in the burgundy Caprise, as the suspect in the shooting, Matteucci said.

A group of young men and women, mostly friends and family of Webber in their late teens and 20s, Matteucci said, had been headed in the three cars from East Palo Alto to San Francisco that night "to hang out," he said.

At some point on the highway, Wilson may have done something on the highway to upset someone in the other vehicles, possibly cutting off or tailgating someone, Matteucci said, resulting in a "freeway altercation," he said. It is not believed that any of the occupants of the three cars knew Wilson, he added.

None of the other occupants of the cars have yet been charged, though the investigation is continuing, Matteucci said. "We don't have information at this point that they even knew that (Webber) was going to do this," he said.

Matteucci credited the arrest to a collective effort between law enforcement, media and private citizens.

"This is a great example of the police and the media and the public coming together to help solve a case," Matteucci said.
