Authorities in Maryland tonight arrested a 29-year-old woman wanted in Philadelphia in connection with the slaying of her 53-year-old mother inside her Cobbs Creek home this morning.

Police said Jahina Damon was in custody in Maryland and was awaiting extradition to Philadelphia to face charges in the death of Lolita Lee.

Police said Damon arrived at Lee's home in the 6000 block of Cobbs Creek Parkway before dawn today and shot Lee and fired at two other people in the house - but missed. Afterward, police said, Damon set the home on fire.

Police were called to the home after reports of gunfire about 5:10 a.m. Arriving officers found heavy smoke coming out of the first floor and notified the Fire Department. The blaze was brought under control at 5:33 a.m.

Lee's body was found in the kitchen, police said. She had been shot at least once in the chest. Firefighters said her body had been burned beyond recognition.

Police said one of the people who had been in the home when Damon arrived was a woman who drove herself to Delaware County Memorial Hospital to seek treatment for serious burns.

She was taken to Crozer-Chester Medical Center, where she was listed in critical condition. The other person in the house during the attack, a man described as the victim's boyfriend, was not injured. Their names were not released.

Police said Damon, whose last known address was her mother's home, has a history of mental illness and has been committed in the past. Police did not talk about a motive for the killing.
