A man walking his dog in Terrell on Wednesday fatally shot an armed 17-year-old robber, police said.
The incident happened at about 10:20 p.m. in Ben Gill Park in the 100 block of Lions Club Lane where, police said, a group of teen robbers surrounded the man.
According to investigators, Markee Lamar Johnson pulled out a gun and the 47-year-old man, a licensed concealed handgun owner, fired shots.
The 17-year-old Terrell High School student was struck in the head and died at Parkland Hospital. His weapon was recovered at the scene and later determined to be stolen during a separate offense in Terrell, according to police.
Police said they would not likely file charges against the man.
"I think in this particular situation, it would be a clear example of someone exercising their rights to protect themselves under the law," Capt. A.D. Sanson said.
Three other teen suspects fled the scene in a vehicle that was recovered in the 300 block of S. Park Street, police said.
Police identified the the other suspects and arrested one of them. Ryan Scott Patterson, 17, is charged with aggravated robbery.
The robbery victim, who did not want to be identified, was not injured.
