PALESTINE, Texas — A 64-year-old woman and four grandchildren were killed early Saturday after a creek overflowed its banks, flooding an East Texas neighborhood as many residents slept.

Captaine James Muniz of the Palestine Police Department said six to 10 homes in a Palestine cul-de-sac were severely damaged following heavy rainfall over the course of just a few minutes after midnight. All other residents of the cul-de-sac were accounted for, he said.

‘‘The water got up here extraordinarily quickly. The individuals tried to get out; however the water was already on the roof of the home,’’ Muniz said

The victims were identified as 64-year-old Lenda Asberry and her grandchildren 6-year-old Jamonicka Johnson; 7-year-old Von Anthony Johnson Jr.; 8-year-old Devonte Asberry, and 9-year-old Venetia Asberry.

Around 3:45 a.m., police received reports that Asberry and her grandchildren were missing and sent officers to search the houses in waist-deep water.

The bodies of two of the children were found in the front yard of a residence near the street. A continued search found the bodies of Asberry and the two other children.

Between 20 and 30 people were displaced by the floods.
