The man suspected of showering bullets into a crowd of concert-goers, wounding hundreds and killing 59 in Las Vegas on Sunday attended and graduated from Los Angeles Unified School District schools in the northeast San Fernando Valley, officials confirmed Sunday.

Stephen Paddock graduated from Los Angeles Unified School District’s John H. Francis Polytechnic High School in Sun Valley in 1971, according to district spokeswoman Barbara Jones.

She said that Paddock also attended Richard E. Byrd Middle School in 1965.

Paddock’s face, which appeared in pictures shown on television news broadcasts Monday, struck many who grew up and went to school with him in Sun Valley as familiar.

One of those people was former Los Angeles City Councilman Richard Alarcon, who posted on Facebook that he realized he may have known Paddock.

“I just recognized his face, his hair color, his eyes,” he said. “He always had big eyes when he was a kid. The face was recognizable.”

“To make matters worse, I had a lot of friends who were at the concert,” he said. “Very strange feeling.”

Alarcon said he played baseball and football with him as children at the neighborhood park as part of an afterschool program. They later both attended John Francis Polytechnic High, and graduated as part of the same class in 1971, though in those years they were not close, he said.

But Alarcon noted that if he “had to pick somebody, (Paddock) would be amongst the last” people that he would have though would be the suspected shooter, he said.

“He was an average kid, very pleasant,” he said. “He wasn’t overbearing … He didn’t have the most outspoken personality. We’re talking about when we were 8 to 12 years old. He was just an average, American kid.”

Many others expressed shock as they drew the connection over conversations in neighborhood Facebook pages, including an alumni of Francis Polytechnic High School. Some posted up yearbook photos, and others calculated the years to see if his age matched up with the graduation year of the Stephen Paddock that they knew growing up.

Cindy Sower, the president of the Sun Valley Neighborhood Council, said that she is among those who grew up knowing the Paddock family and warned they need some privacy, as they are still “in shock.”

“I just know he has a very loving family, and they are absolutely devastated, not for the loss of their brother. If he was going to do this if he was going to take his life, he didn’t need to take anybody with him. His family is just devastated.”
