Authorities say a man fatally shot a Texas sheriff’s deputy in Houston, prompting a massive search involving multiple law enforcement agencies.

A manhunt ended in Texas when a Houston man accused of shooting and killing a deputy serving a warrant on him in the parking lot of a Dollar Tree, was fatally shot by police.

Two Houston area law enforcement officers were killed in the line of duty on Wednesday as Texas leads the U.S. in officer deaths. On Wednesday morning, Brazoria County Sheriff’s Office Deputy Jesus Vargas was shot and killed by a man with an extensive criminal history while attempting to serve a warrant.
