(NEWSER) – Authorities arrested a mother in rural Oklahoma on Thursday for an alleged triple shooting that left her 18-year-old son dead and two teen daughters with critical injuries. Amy Leann Hall, 39, has been booked on one count of first-degree murder and two counts of shooting with intent to kill, Tulsa World reports. A guest who was at the house in Nuyaka about 50 miles south of Tulsa when the alleged shooting occurred helped call 911 around 6:30am, according to KJRH. "We had a 14-year-old female caller who struggled and was able to get a phone call out," Sheriff Eddy Rice said. "There was also a house guest in the house, so that guest also assisted with that 911 call." A motive for the shootings is unknown, according to reports.
Rice said that authorities had visited the house for domestic issues before, but no arrests had been made during those previous visits. The dead teen is identified as Kayson Toliver, a senior running back on the Beggs High School Golden Demons football team. One of the injured girls is identified as Kloee Toliver, who, school Superintendent Brian Terry tells KJRH, is a junior at the school and in critical condition. The third victim, so far unnamed, is said to be in stable condition. At the high school, which has about 300 students, the class schedule remained normal, News On 6 reports, but some after school activities were canceled. "It's a terrible tragedy for the Beggs community," says Terry, adding that counselors were brought in from other schools to talk to students. (Also this week, a Georgia woman killed her mom, son, and herself.)
