There's been another sad development in Bobbi Kristina Brown's health crisis. The 22-year-old's family is said to be coming together this week to reach a final decision about whether or not to terminate life support for Whitney Houston's brain-dead daughter, reports RadarOnline.com.

While several family members are flying to the Atlanta hospital for the summit, the decision will ultimately be made by Bobby Brown and her grandmother, Cissy Houston.

Bobbi Kristina has been in a medically-induced coma since being rushed to an Atlanta-area hospital on January 31. Soon after she was moved to the intensive care unit at Emory University Hospital, where she has remained for six weeks. There have been no signs of improvement in her case.

Meanwhile, there are some other alarming details springing up about the dire situation. Bobbi Kristina's 10-carat, $250K diamond ring, which was wearing on the day she was found unresponsive in her Atlanta home and was gifted to her by her late mother, has gone missing, according to Radar.

According to reports, Bobbi Kristina’s family realized the ring had gone missing after Bobbi Kristina's boyfriend Nick Gordon spoke about it during his interview with Dr. Phil last week.

On the show, Gordon asked his mother about the ring in question, and she said she was keeping it safe. After the interview, a member of the Houston family contacted the Gordons about the ring, but apparently they claimed they were talking about a different ring and not the $250K, a source reportedly said.

Sounds very suspicious to us, but given all we know about Nick Gordon we aren't surprised ...

Police have launched an investigation into Bobbi Kristina's incident after injuries consistent with foul play were found on her body.
