A sheriff's deputy has been shot dead while filling up his patrol car at a petrol station in Houston, Texas.
Harris County Sheriff's Office said Deputy Darren Goforth was putting fuel in his vehicle on Friday night when a man approached him from behind and fired multiple shots.
After the officer fell to the ground, the suspect fired more shots.
Police said they have a description of the male suspect, who was driving a red or maroon Ford Ranger truck, and have begun an intensive search.
Investigators have also been pulling CCTV footage from the service station as they appeal for the public's help with tracking down the killer.
In messages on the force's official Twitter account, Harris County Sheriff's Office said: "Deputy Darren Goforth was a 10-year veteran with the Sheriff's Office. Our hearts are broken tonight.
"This was an unprovoked attack. Deputy Goforth left behind a wife and two children. Please continue to pray during this difficult time."
