( CNN ) -- A Texas woman accused of killing her toddler daughter and dumping the body in Galveston Bay has been found guilty of murder by a jury in Galveston , Texas . Kimberly Dawn Trenor received a life sentence without possibility of parole in the murder of her daughter . Kimberly Dawn Trenor , 20 , showed no emotion as the verdict was read late Monday . Trenor had pleaded guilty to tampering with evidence in the case , but pleaded not guilty to the capital murder charge . She received a life sentence without the possibility of parole . The body of Trenor 's daughter , Riley Ann Sawyers , was found in October 2007 in a large blue plastic container on an uninhabited island in Galveston Bay . Two-year-old Riley Ann 's case drew national attention after a fisherman found her body . Authorities did n't know her identity , and police dubbed her `` Baby Grace . '' After authorities distributed composite sketches of the girl nationwide , Sheryl Sawyers , the girl 's paternal grandmother , contacted police from her Ohio home to say the drawing resembled her granddaughter . DNA testing confirmed the child 's identity . According to an affidavit , Trenor told police Riley had been beaten and thrown across a room and that her head was held under water before she died on July 24 , 2007 . Another piece of evidence shown to the jury during the trial was a page of Trenor 's journal where she talked of beating the child , according to CNN affiliate KTRK . `` I just kept hitting her with the belt again and again . I do n't know how long , but I remember her trying to get away and me knocking her back down , '' the journal said . Trenor 's husband , Royce Clyde Zeigler II , 25 , also faces capital murder and evidence tampering charges , but is being tried separately . A court date has not been set in that case .
