HOUSTON — KHOU 11 has learned the man accused of killing Precinct 7 Deputy Constable Jennifer Chavis is now being held without bond in the Harris County Jail.
On Monday, a judge had set Adolfo Serrano's bond at $750,000, but it has since been denied.
Serrano, who is charged with intoxication manslaughter, is accused of driving drunk when he crashed into the back of Chavis' patrol unit Saturday on Beltway 8 near Fondren, causing her vehicle to burst into flames.
Chavis was positioned to intercept Serrano after witnesses called 911 to report his vehicle veering in and out of lanes, authorities said at the time.
"This deputy was there, ready to get in right behind and stop him," Sean Teare with the Harris County District Attorney's Vehicular Crimes Unit said. "And instead, he crashed right into the back of her."
Investigators said they interviewed Serrano at the hospital and said he admitted to hitting a car on the shoulder.
"The defendant had red eyes, slurred speech ... admitted to drinking an alcoholic beverage," the prosecutor said on Monday.
Serrano has a lengthy criminal history, including a prior DWI conviction.
Prosecutors had asked for Serrano to be held without bond during a Monday court hearing, but his defense attorney argued that Serrano has four sons that depend on him.
The judge initially set bond during that hearing.
