FORT BEND COUNTY, Texas -

Deputies in Fort Bend County are investigating a shooting in which officials say two people were killed.

Neighbors are left shocked and speechless at the incident.

"They are real nice people, never thought that something like this would happen to a family like that," says neighbor Steve Villani.

At around 6:20 a.m., the Ford Bend County Sheriff's Office was called out to the home on 4800 Russet Lane.

"We found two adults deceased and two children wounded," says Bob Haenel of the Fort Bend Co. Sheriff's Office.

"We went outside and we saw a little girl laying on the ground, shaken up, but it looked like she was able to walk around, but there was a little boy under the tree, he was covered up and had a oxygen mask on him, and there was about 10 people trying to resuscitate him," says Villani.

The couple's 15-year-old daughter and 11-year-old son were taken by LifeFlight to Memorial Hermann Hospital. Both children underwent surgery and are listed in stable condition.

Their parents were found dead inside the home from apparent gunshot wounds. A handgun was retrieved at the scene.

The sheriff's office says the shootings resulted from a family disturbance.

Sheriff's deputies are not saying yet who they think pulled the trigger. The case remains under investigation.

Principals at Brazos Bend Elementary and Travis High sent letters home to parents making them aware of the incident. Counselors will be made available at both schools if any students need to talk.
