Three days after a marketing professional was beaten and left for dead outside his suburban Bay Area home, police said that they are questioning "several" teens from two high schools in the city about the attack.
Pleasanton Police Sgt. Maria Munayer, speaking at a news conference Tuesday, declined to say much more about the "active" investigation into a brutal attack on David Lamont, a father, husband and 51-year-old co-founder of Marketingsage who was badly beaten just after midnight Saturday morning on the normally sleepy dead-end Middleton Place.
Munayer confirmed that Lamont went outside his home just before midnight Friday night when he heard "loud voices" and confronted some "juveniles making noise."
She said officers are interviewing teens, whom she described as "persons of interest," and urged community members to come forward if they had any information to share.
Munayer did not specify the number of teens possibly involved and she did not identify the schools attended by the teens being interviewed. Pleasanton Unified School District Supt. Parvin Ahmadi said district is cooperating with authorities, but declined to say more. Lamont's two daughters, Fiona, 19 and Orla, 15, attended and currently attend schools in the district.
The witness who saw an SUV leave the scene just after midnight talked to NBC Bay Area, asking to remain anonymous. He said he was just pulling up to his street when he saw a "golden or metallic brown" SUV pull away from the area. Within moments, a flood of police cars and fire trucks had appeared, responding to an earlier 911 call.
As of Tuesday morning, no one had been arrested and Lamont remained in a coma at Eden Valley Medical Center.

"It's so horrible and so cruel," Lamont's wife, Agnes Lamont told NBC Bay Area on Monday. "The fact that they left him there to die -- I can't understand it."
Lamont was visibly shaken as she recounted how she went to search for her husband of nearly 25 years when he didn't return. She was stunned to find him lying in the street bleeding and unconscious. She is also his business partner; the two co-founded Marketsage in 2002, and had moved to the Bay Area from their native Ireland.
"They've broken our lives," Lamont, who did not attend the news conference at the police station on Tuesday, said on Monday. "My husband is in danger and he did nothing to deserve this."
Sandy McDonald said she thought the beating was "horrible," and she doesn't feel safe herself, a sentiment echoed by others who live nearby, too.
Those who know Lamont are praying that he'l soon recover, and they are remembering him as a vibrant person, devoted father and patent holder, too.
He and his wife helped his daughters get a patent in 2011 for a product they named a "Yuckease," a combination scoop, scraper and container to pick up unpleasant or hazardous items. The family was issued a trademark for this invention in April.
Anyone with information should call Pleasanton police at (925) 931-5100.
