CONWAY, Ark. (AP) — Authorities say an Arkansas woman who adopted her granddaughter after her son's death in Iraq stabbed the 7-year-old girl in the chest and then set fire to their home in a murder-suicide.

Faulkner County sheriff's spokesman Maj. Andy Shock said Monday that 63-year-old Janice Robbins left a suicide note in her pickup truck before killing her and her granddaughter, Abby, on Saturday. Both died of fire-related causes.

He says she wrote that she didn't want to leave the girl behind.

Investigators say there were no signs Robbins was in financial distress and they're looking into whether she sought treatment for depression.

Robbins adopted her granddaughter after her son was killed in Iraq in 2004 by another soldier during a dispute over alcohol.
