Authorities in Berkeley County have arrested a man who they say admitted to killing his 26-year-old girlfriend and her daughter with Aiken County roots, according to the Berkeley County Sheriff's Office.

The bodies of Ashley Kaney, 26, and her 8-year-old daughter Riley Burdick, were found inside their home on Kershaw Road in Summerville about 11:30 a.m. on Tuesday, according to Berkeley County Coroner Bill Salisbury. Salisbury did not want to speculate on the cause of death and said autopsies were being performed this afternoon.

Kaney's boyfriend, 22-year-old Jacob Theopholis Philip, was developed as a person of interest during the homicide investigation, according to a statement from the Berkeley County Sheriff's Office. Philip was arrested by Virginia Beach Police for unrelated charges and confessed to killing Kaney and her daughter.

Philip has been charged with two counts of murder and is being held in Virginia Beach pending local charges and extradition to South Carolina, according to the statement. The deaths of Kaney and her daughter were determined to be the result of “an isolated act of domestic violence.”

The Berkeley County school district sent a social worker to the home to check on Burdick Tuesday morning after she did not show up for school on Monday and Tuesday, Salisbury said. After she knocked and received no answer, the social worker called the Berkeley County Sheriff's Office. Deputies responded and made entry to the home, where they found the bodies.

According to her Facebook page, Kaney is from Aiken and lived in Summerville.

More details about the deaths should be released later today.
