An arrest has been made in the case of an autistic woman who was allegedly abused at a Winthrop group home. Timothy Kabura, 31, of Chelsea, was arrested Thursday on two assault and battery charges, one with a weapon, Winthrop police said. He was a former employee at the home. Kabura is charged with assault and battery on a retarded person, which carries a stiffer penalty than regular assault and battery. Watch Steve Sbraccia's Report NewsCenter 5's Steve Sbraccia reported that 34-year-old Mary Elizabeth Morrow was hospitalized with facial injuries. The victim's family said that they were hurt and upset over her injuries. Morrow has the mind of a toddler and does not speak. "Mary has bruises all over her. She has a black eye. It's terrible," sister Christine Morrow said. "She looks terrible, and she usually looks happy." The family said that this was not the first time Morrow had been injured. A year ago, she also had facial bruises, but an investigation determined that she had not been abused. Both the Disabled Persons Protection Commission and local police are investigating the incident. "When you get a bruise of unknown origin, it's difficult sometimes to determine the cause of that bruise, whether by accident or whether it was caused by someone physically assaulting the individual," Nancy Alterio of the commission said. The company that runs the facility said that it is cooperating with investigators. "Our staff worked very hard to try to take care of all of these folks, and if there's any kind of injury, it's upsetting to everybody," Bruce Bird of the North Suffolk Mental Health Association said. "We feel for the family and everybody involved." Prior to the arrest, three staff members were suspended, pending the outcome of the investigation. "Three staff members have been suspended. Those were the staff who were on duty at the time," Bird said. "It doesn't necessarily mean they were guilty of something, but we have to move in to make sure the consumers are protected while they conduct an investigation." Morrow is improving in the hospital, but her family is still looking for answers. "We try to protect her, we always have, and for something like this to happen, it's just devastating," niece Jaqueline Morrow said. "She's been through too much." In the last year, there have been other complaints at the group home, which were investigated and found to be groundless. Anyone who suspects neglect at group homes should call the Disabled Persons Protection Commission at 1-800-426-9009.
