FORT BEND COUNTY, Texas -- Law enforcement authorities around Houston are investigating two incidents of homeowners using deadly force to protect their property.

Both happened early Christmas morning.

In one instance, a homeowner shot and killed a suspected burglar inside a house on Longleaf Pines Lane in Kingwood.

In Fort Bend County on Malin Court, a man shot and killed someone who was rummaging through his truck.

The sheriff's office there tells us the suspect killed on Malin Court was only 18-years-old.

"The bullet hit the bottom of this bumper right here and they had to retrieve the bullet out of there," said Michael Adams, who showed us where a bullet went through the back of his Lexus Sunday morning.

Investigators tell us Adams' neighbor got off at least three rounds at the suspected burglar--2 of them hit the suspect; another hit Adams' car.

"I feel lucky it hit the bumper versus shattering a window," Adams said.

Fort Bend County Sheriff's deputies tell us a man on Malin Court got up early Sunday to get a glass of water and noticed someone on his security system going through his truck.

The homeowner went outside, and saw something in the suspect's hand. He didn't know what it was and then, according to deputies, saw the suspect make a move toward his waistband.

That is when he opened fire, fearful the suspect had a weapon.

Neighbor Michael Adams, when asked where he was sad about his car having a bullet hole in it, said, "I am sad about my car but you know we gotta look out for each other here because there have been a lot of break ins here."

Investigators are not releasing the name of the 18-year-old suspect. They tell KHOU 11 News his family also lives in the area.

Deputies tell us the homeowner was well within his rights to do what he did to protect his property.
