HOUSTON – A Texas man accused of fatally shooting his neighbor after her dog ran into his yard, may have had a longer term grudge against her, reports CBS affiliate KHOU.

Hector Campos is out of jail on a $50,000 bond after being charged with murder in the death of Ana Weed. KHOU reports that Campos and Weed were next-door neighbors who got into an argument in their front yards after Weed’s dog ran onto Campos’ property.

One of Weed’s relatives told the station that Weed went to get her dog while Campos allegedly ran in to grab a gun and shot Weed in the chest.

Campos is reportedly claiming self-defense. According to his attorney, Campos claims he was assaulted by Weed in what he describes as a “two-handed shove.” Campos also reportedly claims he felt threatened by a roll of tape she was holding in her hand.

Campos alleges that the assault came after months of verbal harassment from Weed’s kids. But Weed’s family disputes those allegations, calling Campos a “dangerous man.” One neighbor told the station that the two had been in arguments before, and that the police were called at least once.

KHOU reports that Campos’ attorney says Campos’ life has been in a “downward spiral” since his wife and 11-month-old daughter “vanished” on what was supposed to be a trip to Mexico. Campos apparently believed Weed helped them disappear, the lawyer told KHOU. Weed’s relatives told the station that Campos’ wife had been a victim of abuse for years.

Neighbors said they couldn’t believe Campos was back at the scene of the crime less than 24 hours after the deadly shooting. He reportedly packed some things and left the home.

On Thursday, Harris County Prosecutor Joshua Phanco explained Campos’ bond by saying, “The bond schedule that’s set in Harris County requires $50,000 on a murder charge for someone who doesn’t have a criminal history, which is what he has. So am I surprised he got a bond? No, because that’s standard in all cases where there is no criminal history.”

A judge decided Thursday that Campos must give up his passport, stay in Harris County, wear a GPS ankle monitor and he cannot talk to the victim’s family or anyone who witnessed the crime, reports the station.

Campos is due back in court in two months.
