More than 100 family members and friends gathered on Monday night to remember an 18-year-old former high school football player who became Campbell's first homicide in more than five years  over the weekend.

The memorial for promising college student Richard Vega was held at Santa Clara High School, where he graduated last year.

The chill on the March night was easier to bear than the chill in their hearts. Family, friends , coaches and teachers gathered on the footfall field where Vega played football for the Santa Clara High Bruins.

His sister, Nancy Vega, spoke of her brother with deep love.

"I thank you guys for remembering him with a big old smile," said Vega. "Remembering him with his crazy jokes and his little ditzy moments."

Vega was attending DeAnza college and working at a Microsoft store. His family said he had an eye on a bright future in Silicon Valley.

That dream was dashed Sunday night as he took a walk shortly before 10:30 p.m. about a block from his family home in Campbell. Someone shot Vega. He died at the hospital.

A neighbor who wished to remain anonymous described what he heard.

"We heard two gunshots and I heard a guy say 'Help me!' It sounded really bad," said the neighbor. "'Please help me!' And I saw him walk along the sidewalk and collapse and I called 911."

Police told KTVU they don't know if the shooting was targeted or random. Loved ones said the devout Christian Vega was simply at the wrong place at the wrong time.

"He never did harm to anybody," said friend Nathan Galindo. "This kid, you couldn't picture him having problems with anybody."

There was laughter along with tears at Monday's vigil. Teachers and coaches told KTVU Vega was quote "a joy" to be around.

Santa Clara High football coach Mark Krail remembered Vega as a teen who always had a smile and often asking about others.

"He'd say 'Hey coach! How are you? How's your day going?' One of those kids," said Krail. "The world need more of those.They do."

Vega's girlfriend Lesley Landaver thanked everyone from showing up at the vigil.

"I know that he loved each and every one of you," Landaver said before turning to hug her slain boyfriend's sister.

Police told KTVU that so far they have no suspects in the crime.
