    MAURY COUNTY, Tenn. (WZTV) — FOX 17 News has disturbing new details about a murder-suicide that shocked Maury County two months ago. Documents revealed that the mother shot 34 rounds into her four children before turning the gun on herself.

    An autopsy shows the mother had no drugs or alcohol in her system when she killed herself. The report says 17-year-old Kaileigh Lin Collier was shot 13 times in the bathroom, 15-year-old Lia Lin Collier shot nine times in her bed, 14-year-old Meigen Lin Collier shot eight times in her bed, and 14-year-old Bo Li Collier shot four times in his bed.

    Two months later, a motive is still unclear to investigators. Court records show the parents went through a nasty divorce; however, the kids seemed to live in a loving household with their adoptive mother.

    Adoption counselor Charlsey Gibson told WZTV the adoption screening process is intense.

    “Lots of questioning, there's references, we do TBI, FBI background checks, DCS child abuse, health, abuse, sex offender registry checks,” Gibson listed.

    She said any indicator of mental illness would have been put under a microscope, but in the end, it’s hard to know what goes on behind closed doors at all times.

    “There's really no way to know what goes on every day, all the time, in the homes of families,” Gibson said.

    The autopsy report indicated the mother left a suicide note, but it does not disclose what was written.
