HOUSTON -

A manhunt is underway for three thieves who investigators say pistol-whipped a homeowner in his own backyard. 

The incident happened at around 1:30 p.m. Wednesday at a home on Campden Hill and Danefield in southwest Houston. The homeowner says he was inside by himself when he looked out the window and saw a man standing in his backyard.

"I thought I was going to die for real. I'm like, 'Oh they're going to shoot me," said the homeowner, Marco Martinez.

Martinez opened his door to see what was going on and that's when things took a turn for the worse.

"And I said, 'What are you doing here?' He pulled out a gun from his waistband and pointed it right at me. He said, 'Get in the house,'" said Martinez.

He started fighting with the man and soon realized he was outnumbered.

"Before you knew it, it was three dudes coming at me and they said, 'If you keep fighting, I'm gonna shoot you, I'm gonna shoot you, I'm gonna shoot you,'" Martinez said.

But he didn't listen, wanting to protect the home he has lived in his entire life.

"I was fighting long enough to where they said, 'This guy's not gonna fall, so let's go.' I guess they weren't trying to kill me because they could have pulled that trigger easily," he told Local 2.

Martinez says he lucked out this time, but he's worried this won't be the last. About a year ago, thieves broke into the same home when nobody was inside and stole precious family mementos.

"I'm tired now. I can't even sleep in peace without worrying about someone breaking in and hurting my family," he said.
