Mindy McCready did NOT attend her boyfriend David Wilson's memorial service on January 19th. She did however sit down for an interview with NBC where she denied killing him.

A friend of Wilson's says, "[Mindy] might have wanted to deal with it in her own way. I think she wanted something more private with her family."

Meanwhile, Mindy did an interview with "Dateline's" Andrea Canning where she talked about being heartbroken, and denied having anything to do with his murder. Asked point blank if she killed David she said, quote, "Oh my god, no. Oh my god, no. He was my life. We were each other's life." Mindy said she started screaming when she saw Wilson after the shooting. Quote, "I lay down next to him and just pleaded with him not to die."

She did admit they argued on the night he died, but insisted that Wilson was not cheating. She said, quote, "David was not having an affair with another woman. That is absolutely, totally untrue." She was also asked about the bullet being found the day AFTER the murder. She had a bizarre answer to that. She said, "I didn't find it . . . the dog did. It was in the dog's mouth. I mean, that's a horrific thing to say, but it was in the dog's mouth."

Mindy has not yet been named as a suspect in Wilson's death . . . and she thinks the sheriff is on a "witch hunt." We'll know more when forensic tests are done in a couple of weeks.  See interview below:
