Did Mindy McCready play a role in her boyfriend's death? As the country singer mourns the loss of the man she called her "soulmate," David Wilson, she is now having to also weather claims that she may have had something to do with his death.

The 34-year-old music producer died Jan. 13 from what was initially declared a self-inflicted gunshot wound. But police now insist the cause of death has not yet been determined.

"This is a very high-profile case and we need to make sure it's investigated as thoroughly as possible. It could take weeks for the state crime lab to complete tests on Mr. Wilson's body, and if you'll notice, it was Mindy McCready's spokesperson -- not anyone involved in the investigation -- who made the determination that Mr. Wilson's death was due to a self-inflicted gunshot wound," Cleburne County Sheriff Marty Moss tells the National Enquirer
