[HIGHLIGHTS] The perpetrator of the Texas massacre had been deported four times

Francisco Oropesa Perez-Torres entered the U.S. illegally several times and was deported four times.

He killed four adults and a 9-year-old boy with shots at close range and above the neck. The reward is $80,000 for any information leading to the arrest of the killer. It's unknown if he currently had his paperwork in order in Texas before he fled, police say. "We don't know where he is," said the FBI agent in charge of the investigation.
