Two women found dead in their Phoenix home last week were strangled with some type of cord, rope or wire, according to the Maricopa County Medical Examiner's office.

A spokeswoman for the Medical Examiner's office told CBS 5 News the official causes of death for Melissa Mason and Nicole Glass were ligature strangulation, or strangulation with a cord-like object.

Phoenix police also said one of the women was pregnant. Friends of Mason told CBS 5 News that she was pregnant.

The bodies of Mason and Glass, both 27, were discovered on the floor of their home near 40th Street and Thomas Road by a friend on Friday.
There were no signs of forced entry, and despite some trauma to the bodies, the cause of death was not immediately obvious, according to police.

Both women had worked at gentleman's clubs in the Valley, although Glass had recently quit and was attending school, friends and co-workers said.

The house had a makeshift memorial of flowers, pictures and candles placed by friends and co-workers on Saturday night.
If the autopsy confirms that Mason was pregnant, that could affect the charges against their killer, according to police.

"Whether that has anything to do with the motive in this case, we don't know," said Phoenix police Sgt. Trent Crump. "However, if it does have something to do with this case and we can prove that, then certainly there are charges within state law that allow us to increase the punishment or even add a victim to this case."
