( CNN ) -- An adoptive mother has been charged with murdering her 9-year-old quadriplegic daughter , prosecutors in Michigan said Friday . An official says Shylea Thomas , 9 , had a `` suffocation issue '' at 3 weeks old that made her quadriplegic . Lorrie Thomas was charged with second-degree murder and child abuse in the death of Shylea Myza Thomas , said John Potbury , an assistant prosecutor with the Genesee County Prosecutor 's Office in Flint , Michigan . Thomas is also charged with tampering with evidence . Thomas , who is the girl 's biological aunt , made no immediate public statement . Police found the girl 's body this week , stuffed inside a garbage bag in a public storage facility in Vienna Township , near Flint , said Genesee County prosecutor David Leyton . The bag was covered in mothballs `` in an apparent attempt to mask odors from the dead body , '' Leyton 's office said in a news release . `` This is a very sad and tragic case that hurts all of us involved in the ongoing investigation , '' Leyton said . Shylea had not been seen in six weeks , but relatives did not report her missing until Tuesday , Leyton 's office said . Thomas had been taken into custody earlier this week and held as a suspect . Because of her physical disabilities , Shylea had to use a feeding tube . She suffered from quadriplegia because of a `` suffocation issue '' in her crib at 3 weeks of age , Leyton said . Leyton said Shylea and other relatives had lived in `` absolutely filthy '' conditions . Relatives told CNN affiliate WJRT that they remember Shylea as a happy child who loved music and had an infectious smile . `` The last memory I actually have of Shylea is seeing her when she was in my care , '' said her second cousin , Josette Thomas . `` She was on the bed listening to the radio and smiling . Those are actually the memories I want to keep in my head . I do n't want that memory to leave me . ''
