Connecticut ? Two men with long rap sheets were on parole when they broke into a doctor’s home in Meriden, strangled his wife and killed the couple’s two daughters in a fire they set to cover their tracks, authorities said Tuesday.

Joshua Komisarjevsky, 26, of Cheshire, and Steven Hayes, 44, of Winsted, were arraigned Tuesday on charges of assault, sexual assault, kidnapping, burglary, robbery, arson, larceny and risk of injury to children. Bail was set at $15 million each, which Judge Christina G. Dunnell said was warranted because of the men’s criminal histories.

The state medical examiner confirmed Tuesday night that Jennifer Hawke-Petit, 48, was strangled and that her daughters, 17-year-old Hayley and 11-year-old Michaela, died of smoke inhalation. All three deaths were ruled homicides.

More charges are pending, state police said Tuesday night.

Dr. William Petit Jr., 50, who escaped the burning home, is hospitalized with head injuries.
