Dorner exchanged vows with his wife in Las Vegas in April 2007, but the union lasted only a few weeks.
According to documents filed with the Superior Court of Los Angeles County, the pair was married from April 27 to May 24, 2007.
Dorner’s ex-wife now lives in Long Beach. Neighbors say he often visited her home.
“I’ve seen him here. I’ve said hi, I’ve bumped [fists] with him a couple times,” said 24-year-old Oscar Gonzalez told the L.A. Times.
“He seemed like a regular guy. He was doing landscaping here in the front for her. He was heavy-built, always in military-style boots,” Gonzalez said.
But Dorner’s frequent visits ended a few months ago, according to Gonzalez.
“He was here for a while, and then he was just gone. It just kind of stopped all of the sudden, two or three months ago,” he told the newspaper.
Meantime, police in Las Vegas are taking extra safety precautions as the search continues for Dorner.
SWAT teams swarmed a Vegas home owned by Dorner on Thursday afternoon. They converged on the home, but found no one there.
Officers would not say what they recovered from the property, which Dorner bought in 2007.
Nevada highway troopers are on high alert, watching for Dorner on roads leading into Las Vegas.
