Singer Mindy McCready Dead At 37

Mindy McCready, a once-promising country singer who publicly struggled with substance abuse and other personal issues, was found dead Sunday of an apparently self-inflicted gunshot wound at the age of 37.

The Cleburne County (AR) Sheriff's Office issued a news release saying McCready was found dead of a single self-inflicted wound on the front porch of a home in Heber Springs, AR.

An insider told E! News that neighbors heard gunshots at McCready's home and called police. "She shot herself and the dog," added the source.

McCready's suicide occurs just over a month after the sudden death of her boyfriend, David Wilson, 34, on Jan. 13. Her children Zander, 6, and her son with with Wilson, 9-month-old Zayne, were taken by authorities after family members questioned her ablilty to take care of them.

McCready had attempted suicide twice before; once in 2005, and by slashing her wrists in 2008.

Her hits include "Guys Do it All the Time", and "Ten Thousand Angels".
