Listen to Mindy McCready on iHeartRadio

Preliminary autopsy results confirm country singer Mindy McCready died from a single gunshot wound to the head last Sunday.  According to E! News, the results made public Wednesday suggest suicide, although Cleburne County authorities say McCready did not leave a suicide note. 

Sheriff Marty Moss tells the website this is still an "ongoing investigation."  He would not comment on whether McCready's boyfriend, David Wilson, left a note before he was found dead at the couple's home in Heber Springs, Arkansas on January 13th.  Wilson's death was initially reported to be a suicide but authorities say it is also still under investigation.
