Sheriff Roger Deeds is not optimistic about the fate of Deputy Lance McLean who was shot in the back of the head Friday morning after answering a 911 disturbance call in Oak Trail Shores. “He’s very critical,” Deeds said Friday night. “He’s basically on life support.” McLean is hospitalized at John Peter Smith Hospital in Fort Worth. The heavily armed shooting suspect, Ricky Don McCommas, 49, of Joshua, was killed in the Granbury City Hall parking lot after a pursuit and shootout with officers. Granbury police officer Chad Davis was wounded in the shootout, but his injuries are not life-threatening, authorities said. The deputy who arrived after the shooting at the OTS residence was able to get the description of the suspect and the vehicle as the suspect was fleeing the scene. The suspect traveled on FM 4 toward Granbury, then turned south on Houston Street where he met a roadblock near the square. The suspect turned right, into the City Hall parking lot. “He stopped and got out of the car and started shooting,” Deeds said. Officers returned fire and killed the suspect. The suspect was armed with an assault rifle and two pistols, the sheriff said.
