The Lewiston driver who police said fatally struck her 17-month-old daughter while backing up on Sunday has lost her license because of an August drunken driving charge.

The Maine Bureau of Motor Vehicles on Tuesday suspended the driver’s license of Taneisha Thomas, 27, of Lewiston, for three years because of a drunken driving charge on Aug. 13, according to her attorney, Adam Sherman.

Thomas, who also has a 2013 drunken driving conviction, had been driving with a conditional license after she was charged with operating under the influence last month.

The suspension goes into effect at midnight, her attorney said.

Thomas struck her 17-month-old daughter, Tiannah Sevey, at around 5 p.m. Sunday at the Pleasant View Acres apartments where a birthday party was being held for another one of her children, according to Lt. David St. Pierre of the Lewiston Police Department. The toddler was later pronounced dead at Central Maine Medical Center in Lewiston.

St. Pierre said Thursday that he does not expect that Thomas will be charged in the death, but added that authorities are still investigating her daughter’s death, and the final decision will lie in the hands of the district attorney.
