Court records show that the woman who police say was fatally shot by her husband before he killed their three children and himself had sought a divorce last month.
Phoukeo Dej-Oudom filed for divorce from her husband, Jason Hagan Dej-Odoum, on May 25. No attorney is listed in the petition.
Authorities say the husband gunned down his wife outside a drug store and killed their children at an apartment before shooting himself Wednesday.
The Clark County coroner’s office said the youngest child, 9-year-old Anhurak Jason Dej-Oudom, died of a gunshot wound to the head.
Also killed were the couple’s 15-year-old daughter, Dalavanh Ariel Dej-Oudom, and 14-year-old son, Xonajuk J.J. Dej-Oudom.
