In a disturbing incident from South Carolina, a woman now faces murder charges following the grim discovery of a man’s body on a roadway earlier this month. The investigation took a significant turn when authorities uncovered a video on her phone capturing a domestic altercation as the man walked down the road.

Charleston County deputies were alerted to the presence of an “unresponsive man” lying on the road. Upon arriving, they discovered the man was “clearly deceased,” with tire marks evident on his body, according to WCIV.

While officials were still at the scene, Phoebe Grace Armstrong, a 28-year-old woman, drove by and was subsequently stopped by a deputy. Armstrong initially claimed she had merely dropped the victim at his residence before heading home herself. However, WCSC reported that GPS data contradicted her account, placing her in the vicinity from 8 p.m. to 8:33 p.m. Furthermore, a video retrieved from her phone showed her driving as the victim walked away from the vehicle shortly before 8:30 p.m.

The investigation deepened with a forensic examination revealing traces of dried blood on the undercarriage and inside the rear wheel well of Armstrong’s vehicle, further implicating her in the tragic event.

A forensics examination found dried blood on the undercarriage of Armstrong’s vehicle and inside the rear wheel well.

Detectives say Armstrong told them she dropped the victim, who has not been publicly identified, off at his home and went straight home on the night of Nov. 30, but further investigation indicated GPS data on her phone showed her to have traveled down Whistler Road and left the area between 8 p.m. and 8:33 p.m.

An affidavit says Armstrong and the man were engaged in a domestic dispute at the time that video was shot and that the two had an “extensive history” of violence in which they were both victims and perpetrators, WCIV said.

GPS data showed Armstrong’s vehicle in the area where the man was found dead and leaving the location. she drove to a nearby Circle K gas station, where surveillance video showed her walking around her car using her cell phone flash light.

She was charged with murder and booked into the Al Cannon Detention Center. She’s being held without bond, jail records show.
