DALLAS -- Police have arrested a 22-year-old man for shooting and killing a Dallas mother who was trying to sell her daughter’s cell phone on buy-and-sell app Offer Up in the parking lot of Medieval Times on the Stemmons Freeway service road.

According to police, 42-year-old Martha Teran had arranged to sell the phone to the suspect, Lonzell Hunter. When she arrived, Hunter allegedly shot Teran and stole the cell phone. Teran’s daughter was in the car at the time of the shooting.

Earlier this week, the victim’s family told us the shooting happened within seconds of the mother and daughter arriving to the meet up. They say there was little-to-no communication before shots were fired.

Teran was taken to Parkland Hospital, where she was pronounced dead.
