At approximately 2:39 a.m. Sunday, officers responded to a “multi-vehicle crash” on Interstate 45 North near the Woodlands Parkway exit, according to the sheriff’s office. The responding deputies were conducting a DWI crash investigation when Deputy Erika Serrato was struck by a heavy-duty commercial truck allegedly being driven by Perez, the sheriff’s office said. Serrato was transported to a nearby hospital, where she was later pronounced dead due to her injuries.
According to the sheriff’s office, Serrato was outside of her vehicle directing traffic at the time of the fatal collision.
“Our hearts are broken today,” Sheriff Wesley Doolittle said in a statement Sunday. “Deputy Serrato made the ultimate sacrifice while serving and protecting our community. We ask that you keep her family, friends, and fellow deputies in your thoughts and prayers during this incredibly difficult time. We grieve alongside them.”
Another deputy at the scene was injured by debris and treated for minor injuries at a local hospital before being released, according to authorities.
Ashton Jammer, 34, who allegedly caused the initial crash before the responding deputies were directing traffic, has been charged with DWI, the sheriff’s office said.
Perez was taken to a nearby hospital following the crash. Neither Perez nor Jammer could immediately be reached for comment.
Serrato, who was assigned to District 2, had worked for the sheriff’s office for six years.
According to the sheriff’s office, the investigation into the second crash, which resulted in Serrato’s death, has been taken over by the Texas Department of Public Safety.
