Authorities say the three suspects involved in a gun battle with Fort Worth police that left an officer critically wounded have lengthy criminal histories and are suspected in series of robberies that primarily targeted Latino bars.

Police Chief Joel Fitzgerald told reporters that the suspect killed in the exchange of gunfire early Friday outside a bar was Dacion Steptoe.

Authorities say it was Steptoe who shot undercover officer Garrett Hull in the head as Hull and other officers approached Steptoe and two other suspects when the trio left the bar after robbing it and the 10 people who were inside at the time.

The other suspects were apprehended and Fitzgerald identified one of them as Samuel Mayfield, who was wanted on warrants for theft, assault and drug possession.

Hull, who has a wife and two daughters, is in critical condition at a hospital.
