Two additional suspects have been arrested in Texas, accused of aiding Oscar Rosales, the prime suspect in last Sunday’s shooting death of a corporal with the Harris County constable’s office, according to police.

The newest arrests bring to five the total number of suspects in the case.

Cpl. Charles Galloway, 47, a Harris County Precinct 5 Constable deputy, was shot dead while conducting a traffic stop in Houston around 12:30 a.m., authorities have said.

Investigators earlier this week identified Rosales as the gunman and authorities in Texas charged him with capital murder of a police officer after he was apprehended in Mexico on Wednesday and returned to Texas.

Courtroom outburst

Rosales, 51, made a second court appearance Friday morning and was much quieter than during his first appearance in probable-cause court Wednesday night, FOX 26 reported. He was being held without bond, the report said.

"Right here, all the officers and the security guard … if they want to try kill [sic] me right here, they can do it, whatever, I don’t care," Rosales shouted in a courtroom outburst Wednesday night, according to FOX 26. "Everybody in this room is waiting for the chance to hurt me."

Rosales’ next appearance in court was scheduled for 11:30 a.m. Feb. 23, FOX 26 reported.

Authorities have also arrested four other suspects in connection with the case, according to Houston police.

Two suspects – identified as Reina Marquez, 40, and Henri Marquez, 42 -- were charged earlier this week with tampering with evidence.
