The death of David Wilson is under investigation after Mindy McCready's boyfriend, "soul mate" and father of her baby died January 13 of a gunshot wound.
David Wilson died at his home in Heber Springs, Ark. Local and state authorities are still trying to piece together what happened before they put the case to bed.
Cleburne County Sheriff Marty Moss said in a statement:
"The body was submitted to the state crime lab for an autopsy along with some other items for testing and at the time that those things are released, we have no control."
"I can't tell you when it will be back."
"It is an ongoing investigation and there are things we are looking into like any other investigation," Moss added, not stating a timetable for answers.
He would neither confirm nor deny the latest round of reports that Mindy is not a suspect; McCready denied killing her partner last week.
The "Guys Do It All the Time" singer, when asked point-blank by NBC News this week if she shot Wilson, replied, "Oh my God, no. Oh my God, no."
"I've never gone through anything this painful," the oft-troubled country singer told the network, "nor will I ever again go through anything as painful."
McCready, mother to their 9-month-old son Zane, did not attend a memorial for Wilson in Fayetteville, Ark., organized by some of his college buddies.
She said that a group of his friends getting drunk in memory of their late pal was "not something appropriate for me and my children to be a part of."
Mindy also has another son, Xander, with Billy McKnight.
She expressed the desire to set up a foundation or scholarship fund for music education in Wilson's name, saying, "David loved music more than anything."
