Texas Department of Public Safety officials say Cuero police Sgt. Corey Tolbert was charged Friday with aggravated assault with a deadly weapon causing serious bodily injury/family violence.
Jail records for DeWitt and Lavaca counties show Tolbert, with bond at $200,000, was no longer in custody Monday.
Texas Rangers helped investigate the April 17 incident when Trooper Elizabeth Tolbert allegedly was struck. KAVU-TV reports the trailer rolled over her legs. The Victoria Advocate reports the trooper spent several days hospitalized.
Jailers had no attorney information for Corey Tolbert, who's on paid leave. Police didn't immediate comment.
A DPS statement didn't release details on the victim.
