Guatemala’s Oscar Rosales arrested in Mexico, accused of shooting Charles Galloway in Houston, Texas


Oscar Rosales, 51, a citizen of Guatemala, has been arrested and charged with capital murder of a policeman/fireman, which is a first-degree felony. He is accused of fatally shooting Charles Galloway, 47, a constable deputy with Harris County Precinct 5 in Houston, Texas, United States.

Rosales is not a U.S. citizen. Reina Azucna Pereira Marquez, 40, has been his common-law wife since 2004.

Galloway was a corporal and a field training officer. He joined Harris County Precinct 5 in 2009.


On the midnight of January 23, 2022, Rosales picked up a white Toyota Avalon from the home he shared with Marquez and left his white Dodge Ram pickup in their driveway. He took two long guns with him, which he had kept in a safe, and told her he was going hunting or shooting with friends.

At around 12:24 a.m., Galloway conducted a traffic stop on the white Toyota Avalon, which was registered to Marquez. Rosales stopped on Beechnut Street in Houston, used a rifle to shoot the constable deputy multiple times and fled the scene.

Galloway was pronounced dead at the scene. At 3:38 p.m., detectives learned that the white Toyota Avalon was parked at an apartment complex at the Falls of West Oaks in Houston, which was leased to Marquez’s brother Henri Mauricio Pereira Marquez, 42.


Investigators caught Reina and Henri removing items from the white Toyota Avalon. The siblings were arrested at the scene and charged with tampering with evidence.

On January 24, 2022, a $60,000 reward was offered for information that would lead to the arrest of Rosales. The reward included donations from the 100 Club’s Fallen Heroes fund and Tilman Fertitta, a businessman from Houston.


On January 26, 2022, Rosales was found in Ciudad Acuna, Mexico, which is right across the Mexico-U.S. border from Del Rio, Texas. He was transported to the Val Verde County Sheriff’s Office in Del Rio a little after 12:00 p.m. and was transported back to Houston shortly before 4:00 p.m.

“This is senseless,” CNN quoted Houston Police Department chief Troy Finner as saying. “It makes no sense whatsoever.”

Rosales previously lived under another name. Between 1996 and the fatal shooting of Galloway, Rosales was wanted for murder in El Salvador.
