HOUSTON — Houston police have identified the suspect in the weekend shooting death of a Precinct 5 corporal.
"He's a very dangerous individual and we're gonna move his butt off the streets as soon as we can," Finner said.
Investigators believe Rosales is still in Houston and are following up on every tip they receive.
“Mr. Rosales, you can run but you can not hide,” said Harris County District Attorney Kim Ogg.
"This is a ruthless, savage execution and somebody like this needs to be removed from the streets and removed from the streets very quickly. But we cannot do it without the help of the public," Pct. 5 Constable Ted Heap said.
A $60,000 reward -- including $50,000 from Rockets owner Tilman Fertitta -- is being offered for information leading to the arrest and conviction of Rosales.
"We need the eyes and the ears of all of our citizens to help us bring this suspect in custody," Finner said.
The chief said they have evidence that Rosales is known to disguise his appearance and they believe he is still in Houston.
Galloway died after he was shot multiple times with an assault rifle during a traffic stop early Sunday.
Galloway had pulled over the suspect in the 9100 block of Beechnut Street. Witnesses said the suspect got out of his vehicle and opened fire on Galloway's patrol unit before driving off. Video from Air 11 showed multiple bullet holes in the windshield of the unit.
The chief said two of the suspect's relatives -- common-law wife Reina Marquez and her brother Henri Marquez -- are charged with tampering with evidence in connection with the case. Finner said they were tampering with the Toyota Avalon that Rosales was driving. The vehicle has since been recovered.
Court records show both Reina Marquez and Henri Marquez were arrested on Sunday.
“Anybody who’s assisting him, a felon, and they know he’s a felon wanted for capital murder, we’re coming out for them as well,” Finner said.
District Attorney Kim Ogg said during the conference that Henri was Rosales' brother. KHOU 11 has since confirmed that Henri is related to Reina.
Harris County District Attorney Kim Ogg said once Rosales is in custody, they will ask that he be held without bail.
"He is a bold and incredibly dangerous fugitive," Ogg said.
She said they have "cast a net far and wide" with law enforcement agencies across the country on alert for Rosales.
Galloway, 47, was a 12-and-half-year veteran with Harris County Precinct 5, assigned to the Harris County toll road division. He was working nights so that he could train deputies.
According to Heap, Galloway was a mentor to young law enforcement officers, teaching them how to be safe and efficient on the job.
The Houston Police Department is handling the investigation.
