MAGNOLIA, Texas -

Deputies are looking for a gunman who they say hunted down his victim and shot him to death.

Officials said the shooting happened shortly before 10 p.m. Sunday in in the 3000 block of Meadow Edge Drive in Magnolia in Montgomery County.

Investigators said Ramundo Zarate Jr., 43, fought with his killer at a park on F.M. 2920 in northwest Harris County. Deputies said Zarate then drove to his home in Magnolia where the suspect followed him and they continued to argue in Zarate's driveway.  According to investigators, the suspect went to his car, got a gun, and shot Zarate once in the head and once in the abdomen. 

Several family members told investigators they witnessed the shooting and tried to get Zarate to the hospital but car trouble slowed them down.  Family members got Zarate into another car and took him to the emergency room at Tomball Regional Medical Center, where he died from his wounds. 

Zarate left four children behind.

The suspect was only described as Hispanic and driving a green four-door car, possibly a Chevy Cavalier. He also had lots of tattoos.

Anyone with information is asked to call Montgomery County Crime Stoppers at 800-392-STOP.
