NEW CANEY, Texas- One man was killed and another was injured after a hit-and-run at at a birthday party in New Caney early Sunday morning, authorities said. The victim has been identified by family as 28-year-old Roy Jasso.

According to the Montgomery County Sheriff's Office, they responded to a disturbance call at a birthday party in the 15800 block of Emerald Court Way around 12:30 a.m.

Upon arrival, deputies found two men were struck outside the residence by a vehicle that had left the scene.

Jasso was taken to Conroe Regional Hospital where he later died; the other man is in stable condition.

Witnesses say Jasso was with his two daughters. He placed them in a pickup truck to protect them when the fighting began. The little girls saw their father get run over.

"He didn't deserve to be killed like that," said Cindy Jasso, the victim's mother.

Jasso's father is pleading with the public in helping find his son's killers.

"I lost my kid and now I need people to help me get justice," said Santiago Jasso. "What they did to him was unfair."

Investigators said 80 to 100 people were at the party and popping fireworks when several uninvited men started a disturbance which got physical. The victims were hit by the car when those men left the party. Authorities said there "was a lot of alcohol involved" at the party.
