Kim Porter's cause of death is a mystery

The Los Angeles County Coroner has called for an "additional investigation" into the death of Kim Porter. The coroner was unable to conclusively determine her cause of death.

It's now been more that two days since the untimely death of Kim - a model, actress and longtime girlfriend of Sean "Diddy" Combs. Kim's body was discovered at her Toluca Lake mansion.

MTO News has confirmed that her cause of death is currently "deferred" for further testing.

As previously reported, Porter was said to be receiving medical treatment for pneumonia prior to her passing. First responders were called to her Toluca Lake, Calif. home on Thursday over a potential cardiac arrest episode. 

Porter was pronounced dead after being found unresponsive in her Toluca Lake home, on the 10300 block of Woodbridge Street, at 11:40 a.m., Los Angeles County coroner’s officials said.

Diddy and Porter, a former model and occasional actress from Georgia, were a couple on-and-off from 1994 until they split for good in 2007.

Their children are a 20-year-old son, Christian, and 11-year-old twin daughters, D’Lila Star and Jessie James. Combs also has three other children from other relationships.

As an actress, Porter appeared on the TV series “Wicked Wicked Games” in 2006 and 2007 and in the film “Mama I Want to Sing” in 2011.

Many in the hip-hop community were mourning her and offering condolences.

Missy Elliott called her death “so heartbreaking,” tweeting, “Lord please give her kids & her whole family strength.”

50 Cent tweeted that Porter “was loved and will be missed dearly.” ”I know Puff is hit up right now,” he said, “he loved her for real.”
