Car mechanic Jimmy Martinez's dog could not save him this time.
Martinez, who credited his dog with thwarting an attack over a parking space dispute on Dec. 4, was shot to death in a separate incident less than three weeks later, according to CBS News and The Associated Press, WROC reported.
During the first incident, Martinez had sustained a gunshot wound to the arm when his young adult pit bull, Chata, charged the assailant. A bullet grazed the dog's nose, but both were recovering after the attack.
Martinez said he owed his life to his canine companion.
"If it wasn't for the dog, I wouldn't be here," he told KPIX at the time, WROC reported.
On Dec. 22, Martinez was not so lucky, as police in Oakland discovered him gunned down outside his RV, according to WROC.
Oakland authorities say an unknown assailant shot Martinez following an argument. Other residents living in nearby RVs reported hearing gunfire at around 9:30 p.m.
"I was about to eat and watch TV," said neighbor Marvin Morris, who reported hearing approximately 10 shots.
"His dog is a super dog, wonder hero," said Duncan Burns, another neighbor who also reported hearing the gunfire. "The dog was locked in the house [and] couldn't get out to help."
Authorities do not believe the incidents are related, but an investigation is ongoing.
Martinez made a living as an independent mechanic, fixing people's cars on the street.
A witness, Hyo Song, reported that a few hours prior to the shooting, a customer confronted Martinez about a bad repair job, demanding a refund, according to The Mercury News.
"They had a little argument, a confrontation for about 5 or 10 minutes," said Song, who works across the street from the location in which the incident occurred. "And then, the other gentleman drove off very angry."
Police are looking for the customer while also examining other potential leads.
For the time being, Chata is staying with Martinez's sister, Diane.
Interviewed by KPIX after the Dec. 4 incident, Diane heaped praise on the dog, WROC reported. "If it wasn't for Chata, I wouldn't be standing here, I would be planning a funeral for my brother."
Sadly, as the investigation continues, those plans will move forward after all.
The nonprofit pet assistance group PALS East Bay had previously set up a GoFundMe campaign to assist with medical bills from the Dec. 4 shooting, according to The Mercury News. The campaign raised more than $8,500.
It's devastating news," said PALS East Bay spokeswoman Nicole Perelman. "We're devastated for his family. It's very sad and tragic."
