Johnie P. Nichols, 73, and Leah Hope Nichols, 3, both of Booneville, died in the crash which happened Saturday around 12:30 p.m. on the parkway.
Parkway officials report Johnnie P. Nichols was driving a 2010 Ford F150 southbound on Trace when the vehicle crossed the center line and struck a bridge abutment. The truck then went down an embankment and landed upside down in a creek where it was almost completely submerged due to the large amount of water in the creek from recent heavy rains.
Johnnie P. Nichols and Leah Hope Nichols were unable to escape from the overturned vehicle.
Two other passengers in the vehicle, Allen Nichols and Kayla Nichols, escaped from the crash. They are the parents of Leah Hope Nichols and the son and daughter-in-law of Johnnie P. Nichols.
Funeral arrangements for the grandfather and granddaughter were incomplete Monday with Kesler Funeral Home in Baldwyn.
