HOUSTON -

The number of carjackings in Houston is up 10 percent since this time last year.

Over last weekend there were two carjackings just blocks away from each other in Southwest Houston.

Rogeilio Garcia was carjacked right outside his apartment on Hillcroft Saturday morning.

"He told me, 'this is a real gun. If you don't believe me, okay,' and he made a shot in the sky," said Garcia.

Garcia followed his gut instinct and he hit the ground.

"They were like, 'give me everything, give me your phone, wallet, everything,'" said Garcia.

Garcia was kicked and punched, but he escaped with his life. Another man was carjacked Sunday morning, on Windswept.

"They took the cell phone, money and the car," said the victim's friend, Alirio Perez.

Perez's friend had just parked his car outside of his apartment.

"He was coming from church when there was two people that came over and pointed a gun on him," said Perez. Fortunately his friend wasn't physically hurt.

These two incidents aren't just isolated cases. Each year, carjackings traumatize hundreds of lives in Houston.

According to the Houston Police Department, compared to this time last year, carjackings are up 11.6 percent citywide. In 2012, from January to July, the city saw 475 carjackings. In 2013, there have been 528.

"It really pissed me off because we work hard to make our money," said Perez. He added, "Other people come over and get away the easy way."

Right now investigators are trying to figure out if the two cases are connected.

"So, now I don't have a car, and I have to work, so maybe I'm not the only one, but it's really hard," said Garcia.
