Elmer Manzano, 51, faces capital murder and attempted capital murder charges in the death of Houston police Sgt. Harold Preston and the shooting of officer Courtney Waller, respectively.
They were shot during a domestic violence call at an apartment complex, according to court documents obtained by Fox News. Manzano also is charged with aggravated assault.
Preston was a 41-year veteran of the police force. Waller has been with the department for three years.
Harris County District Attorney Kim Ogg filed a request for a court hearing to ask that that Manzano be denied bail. The filing also noted that there is strong evidence he will "probably be punished by the death penalty," Ogg's office told Fox News.
The officers were responding to an apartment complex in southwest Houston after Manzano's estranged wife said she was moving out and wanted to get some things from inside. They spoke with the woman and her 14-year-old son in a parking lot for about an hour before the boy unlocked the apartment door and alerted officers that his father had a gun.
Manzano is accused of opening fire and hitting Preston, Waller and his son. Preston was shot multiple times. Waller and the boy are expected to recover. Manzano surrendered to authorities after barricading himself inside the apartment.
Officers went to the residence twice last weekend for domestic issues, Houston police Chief Art Acevedo said Tuesday. After the shooting, critics said Manzano should have been charged after the earlier responses.
In a statement, Ogg's office said any attempt to blame prosecutors for Tuesday's shooting is "sadly political and not factual."
"The only person responsible for this horrible crime is the killer himself," the statement reads. "The record speaks for itself; the officers in these cases didn't believe that a crime had occurred and that left no evidence on which to base any charges."
Manzano, a Salvadoran national living in the U.S. without documentation, has at least four arrests, including assault and unlawfully carrying a firearm, dating back to 1994, according to media reports.
