Authorities say preliminary autopsy results confirm country music singer Mindy McCready's death was a suicide.
The Cleburne County sheriff said in a statement that results from Arkansas' state crime lab show Mindy's death was a suicide from a single gunshot wound to the head.
Investigators have said Mindy apparently shot and killed her late boyfriend's dog before she turned the gun on herself on Sunday at her home. Authorities found Mindy's body and the dog on the front porch where her longtime boyfriend, musician David Wilson, died last month of a gunshot wound to the head.
Authorities are investigating David's death as a suicide but haven't determined an official cause of death yet.
