HOUSTON -

Police are searching for armed men accused of targeting women in parking lots of busy southeast Houston shopping centers.

One shopper was waiting for her sister in the Almeda Mall parking lot Monday morning when three men pulled up in a truck. According to the shopper, two of the men got out of the truck and began looking in her car.

"I saw him looking down at my purse and I was like, 'No, no, oh no,'" said Rachel Butler.

Butler wasn't worried about her purse. She said her 7-week-old nephew Cory was in the back seat.

According to Butler, one of the men pulled out a gun and said, "I have a gun and I will kill you if you don't give me your money."

When Butler began to drive away, she said the robbers tried to block her in with their truck, but that didn't stop her.

"I turn it on and I got to put it in drive and he like yells something at the guy in the truck, and they try to block me in like I can't move. And then I went, 'What the heck,' put it in reverse, use all my gas, almost hitting him, and I wouldn't have minded if I did," said Butler.

About 10 minutes later, the same men in the same truck tried to rob a woman in a Walmart parking lot about half a mile away on Rowlett Road near Interstate 45 South.

The woman was walking through the parking lot when one of the men pointed a gun at her and demanded her purse, but she didn't give it to him, authorities said.

According to investigators, the woman simply walked into the store.

The three would-be stick up men drove off empty-handed, but they're still on the street.
