COUNCIL BLUFFS, Iowa (AP) — The father of a Council Bluffs woman who was killed in a hit-and-run crash has addressed members of the Congress, speaking about losing his daughter and questioning the handling of her suspected killer. KMTV reports Scott Root testified before a U.S. House committee Thursday about the events following the January death of his 21-year-old daughter, Sarah Root.

Investigators say 19-year-old Eswin Mejia was in the country illegally when he was driving drunk in Omaha and crashed into Root’s car, killing her. Authorities haven’t seen Mejia since he posted bail and was released from jail in February. He’s on the Immigration and Customs Enforcement’s list of most wanted suspects.

Scott Root said his family wouldn’t stop until local and federal officials are held accountable and Mejia is caught.
