When Don Marshall heard his front door being kicked in, he said he was struck with terror.
"I'm paralyzed from here down," he said, pointing to his chest. "If you throw me on the floor, all I can do is crawl."
Quick thinking saved the Huntleigh Park neighborhood resident's life.
"When they kicked the door in, I hit the Life Alert ... and it's real loud," Marshall said.
The criminals fled, and Marshall was just thankful to have narrowly escaped the fate of his former neighbor.
"They beat him up bad all the way around the house. I don't know if it was a gun, but they put staples in his head," Marshall said.
A couple days later, another man who couldn't put up a fight, Nelson Daniel, was the victim of a violent carjacking.
"I think they're definitely targeting the individuals who live over here because a lot of them are very defenseless," said resident Claudette Willams.
Williams said she barricades herself in at night and said many of her neighbors are having a hard time sleeping.
"They're depending on getting us and preying on us like predators. They're predators. They're the lowest of the low," Marshall said.
The Huntleigh Park neighborhood is exclusively designed to be wheelchair-accessible.
Part of the problem is that there are no fences and, according to property manager Berry Muth, there is not enough light at night.
Residents are also hoping for increased patrols in the area.
"I know ... every shift patrol will actually go out, patrol by that area and then our SAFE officers will saturate that area, look for any suspicious activity," said San Antonio police spokesman Officer Matthew Porter.
Porter said police have arrested two suspects in the carjacking case, but they are still looking for leads in the other two incidents and encourage anyone who might information to come forward.
