ST. CHARLES COUNTY • A Wentzville man has been charged with four felonies after police say he shot his ex-girlfriend and her father Saturday on the parking lot of the Mobil Service Station at Highway N and Z.

Aaron Dewayne Andrews, 21, of the 1400 block of Hepperman Road, is charged with three counts of first-degree assault and one count of unlawful use of a weapon.

The woman, 18, had separated from Andrews in April, but they had been communicating by phone and arranged a meeting about 11 p.m. on Saturday at the gas station, police said.

The former girlfriend and a female friend went to meet Andrews. Andrews and his ex argued, and he displayed a .22-caliber handgun and threatened both of them, police said.

The women contacted the ex-girlfriend's 37-year-old father and brother. The men drove to the service station and got involved in a physical confrontation with Andrews.

Andrews shot the father; the bullet grazed his nostril and entered then exited his cheek, police said. Andrews then fired at his ex-girlfriend, wounding her in the left thumb and shoulder, as well as the neck and face.

Andrews pointed the weapon at his ex's brother next, but according to witnesses, he had run out of ammunition.
