MOUNT PLEASANT, SC (WCSC) - A 16-year-old boy has been charged with fatally stabbing a 17-year-old male in Mt. Pleasant Sunday evening.

Mount Pleasant Police responded to reports of a stabbing in the 1600 block of Baltusrol Lane in Park West around 7:04 p.m. Sunday.

According to the Charleston County Coroner's Office, Lucas Cavanaugh of Sullivan's Island died at the scene from a stab wound.

Court documents state Matthew Fischer was visiting his girlfriend in Park West Sunday evening when he saw she received a Snapchat from Cavanaugh on her iPod. Fischer then used his girlfriend's iPod to message Cavanaugh, eventually saying "Come over" and "I'll kill you man," affidavits state.

According to documents, Cavanaugh arrived at the residence and the two got into a physical altercation. During the fight, Fischer pulled out a knife from his right pant pocket and stabbed Cavanaugh in the torso, investigators say.

Court papers state Fischer fled the scene in a car and called his mother, who pick him up and brought him back to where the stabbing occurred.

Police say Fischer confessed to the stabbing on video, and provided a written confession.

In addition to murder, Fischer has also been charged with possession of a knife during commission of a violent crime.

Bond was denied Monday morning on the charge of murder.

Charleston County School District officials say grief counselors will be available on Tuesday at Wando High School where both Fischer and Cavanaugh were students.
