A grisly mystery in Pittsburgh: Two sisters of an Iowa state lawmaker were found shot to death at their home in the city, and police are treating the deaths as a double homicide. The bodies of pediatrician and psychiatrist Sarah Wolfe, 38, and teacher's aide Susan Wolfe, 44, were found after the older sister failed to show up for work, reports the Post-Gazette. Both had been killed by a single gunshot to the head and their car was found parked almost a mile away.
The sisters had other injuries, but "I'm not willing to talk about their other injuries other than to say that they did not contribute to their deaths," says the medical examiner, who declined to say whether the women had been sexually assaulted. Iowa state Rep. Mary Wolfe, the oldest of eight children, says the family, most of whom live in Iowa, is "heartbroken, but grateful" for the sympathies it has received, CNN reports.
