A Long Island man has been arraigned on murder charges in connection with the deaths of two women in the 1990s whose naked bodies were found in the woods.

John Bittrolff of Manorville pleaded not guilty Thursday in a Riverhead court. He's been indicted on two counts of second-degree murder.

Suffolk County police say the nude bodies of 31-year-old Rita Tangredi and 20-year-old Colleen McNamee were found within three months of each other in wooded areas of East Patchogue and Shirley.

Authorities say detectives at the crime scenes in 1993 and 1994 recovered DNA evidence linking them. They say that this year, police recovered DNA evidence linking Bittrolff to the cold cases.

Both women had been strangled and suffered head injuries.

The investigation is ongoing.
