The former model traveled to Florida from her home in Nashville to undergo liposuction and to remove previous breast implants. Her physicians at home cleared her for the surgery and she was released from the facility at around 7pm on March 21. Mary was taken to a recovery facility, where she “suddenly” became unresponsive the next day. She was rushed to a local hospital and passed away in the emergency room.

The cause of death was revealed to be “pneumothorax due to perforated parietal pleura during liposuction with autologous fat reinjection procedure.”

Mary suffered a collapsed lung that was punctured during her surgery, according to People.

We’re sending our continued thoughts and condolences to Mary‘s loved ones during this difficult time.
