CHIRENO, Texas (AP) - Investigators say a woman and two of her grandchildren have been killed but another grandson survived a one-vehicle wreck in East Texas.

The Department of Public Safety says the accident happened late Monday near Chireno, about 150 miles northeast of Houston.

DPS says 54-year-old Annie Diggles Jones of San Augustine apparently was speeding when her SUV went out of control on a curve and hit a tree. Jones and 12-year-old Armontay Woods died at the scene.

Trooper John Henley says 14-year-old Anfernee Diggles was pronounced dead at Nacogdoches Memorial Hospital.

The Nacogdoches Daily Sentinel reports 11-year-old Amauryia Diggles was hospitalized in good condition late Monday. Hospital officials did not immediately provide an update Tuesday.

DPS says the woman and the youngsters were not wearing seat belts.
