HEMET (CBSLA.com) —  Hemet residents say a double shooting between neighbors on Wednesday was sparked by a months-long argument over a barking dog.

CBS2/KCAL9’s Crystal Cruz spoke to a man who only wanted to be identified as “Reggie.” He says his 68-year-old foster father shot his next-door neighbors after they confronted his dad at his home.

“I used to think people can’t go crazy over stuff like that. Here’s living proof today,” Reggie said.

He says his dad has been in a longtime feud with their next-door neighbors over their barking dog.

Reggie says the two neighbors showed up on his father’s porch and the pair didn’t like what his dad had to say: ” ‘I’m asking you to quiet your dog up and get off my property.’ They didn’t want to leave and stood there like he was robo-man, with his hands on his hips.”

Hemet police say Reggie’s foster dad shot the two neighbors, one in the head and the other in face. Both have non-life-threatening wounds.

“I’m standing by my dad 100 percent because all this [expletive] could’ve been prevented,” Reggie said.

Neighbors describe the suspect as a hot-head, known for waving guns around and yelling at other residents if their dogs barked.

A resident who only wanted to be identified as Steve said, “He wanted to make sure that everybody knew he was in charge whenever he stepped outside.”

A woman living nearby said she was aware the suspect had guns and “knew this was going to happen eventually.”
