Deputy Erika Serrato's family filed a suit almost two months after the MCSO deputy was hit and killed while assisting with a DWI crash on I-45.
Montgomery County deputies said 29-year-old Bradley Orton had been previously arrested for an indecent assault case in 2022 before the alleged incident this month.
Officials said the three family members were exposed to another confirmed case who traveled from out of state.
The caller told Montgomery County deputies he had shot his brother.
Investigators said it uncovered evidence such as texts in which the suspect acknowledged his actions and apologized.
Liberty County authorities said the 31-year-old inmate escaped custody on foot while being treated at an emergency room in Kingwood.
