LITTLE ROCK, Ark. (AP) -- Authorities say they've sent electronic devices to Arkansas' state Crime Laboratory as they search for clues in country music singer Mindy McCready's apparent suicide.
Cleburne County Sheriff Marty Moss said Tuesday that investigators did not find a suicide note at the Heber Springs home where the performer's body was found Sunday.
But he says they've submitted electronic devices to the state crime lab.
Investigators say it appears McCready shot and killed her late boyfriend's dog before she turned the gun on herself Sunday. Authorities found McCready'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 both McCready's and Wilson's deaths as suicides but haven't determined official causes of death yet.
