David was viciously beaten early Saturday outside his home. It's bad enough that something like this happened in this otherwise quiet neighborhood, but now we're learning from police that they are questioning some local high school students they believe were somehow involved.
"I will say that our persons of interest do attend both of our local high schools," said Pleasanton police Sgt. Maria Munayer.
Pleasanton police are only calling them "persons of interest" but did acknowledge that they are interviewing teenagers from both Foothill and Amador Valley high schools to see whether they have information about the beating that left David in a coma.
"We credit the community for coming forward and continuing to come forward and giving us some credible tips to follow up on," said Munayer.
David's wife found him unconscious after he went outside their home on Middleton Place to ask some teenagers to keep the noise down. Agnes Lamont told us she and her husband could hear young voices, male and female, outside their home.
"I really appeal to anybody that knows anything. People know this. They know what happened. Please, please talk to the Pleasanton Police Department, tell them what you know," said Agnes.
"I noticed some headlights had turned on at the top of the street," said one neighbor, who did not want his face shown. He told us he came home to see an SUV driving past him from the top of the cul de sac. He said, "I saw a gold or metallic brown SUV drive down the street. I saw a silhouette of a driver and I thought I saw some activity or movement in the back of the vehicle."
Neighbor Sandy McDonald says she won't try to handle noise issues herself from now on. She told us, "I'm sure this fella that went out to investigate the noises or whatever was going on, certainly didn't think this was going to happen."
The superintendent of the Pleasanton Unified School District, Parvin Ahmadi, told ABC7 News, "We will cooperate with police as needed. Our hearts go out to the family of the victim and we continue to pray for him and keep him in our thoughts."
Anyone with information is asked to contact Pleasanton police.
