Investigators have determined the Sangaree woman killed along with her 8-year-old daughter last month died as a result of her oxygen supply being cut off.

Ashley Kaney, 26, and her 8-year-old daughter, Riley Burdick were found dead inside their Kershaw Road home on Oct. 1, according to investigators.

Burdick was found strangled in her bed, but Kaney’s cause of death was pending an autopsy. The results of that examination were released by the Berkeley County Coroner’s Office on Friday.

Kaney’s death has been ruled as a homicide and the cause of death is traumatic asphyxia, coroner’s officials said.

Coroner Bill Salisbury said the asphyxiation occurred as a result of compression, squeezing against the air supply.

He would not provide further details or say what, if any object, was used.

Kaney’s former boyfriend, Jacob Theopholis Philip, a student at the Nuclear Power Training School in Goose Creek, is charged with two counts of murder in their deaths.

He’s currently detained at the Hill-Finklea Detention Center in Moncks Corner.
