ROTTERDAM - The bodies of Tammy McCormack and her daughter Jessica were found on April 10th in their bedrooms on Inner Drive in Rotterdam.
It wasn't long before Jessica's on-again, off-again boyfriend, Brice Rivenburgh, was arrested on a burglary charge.
But now, authorities say Rivenburgh killed the mother, and raped and killed the daughter, and stole a television, then came back hours later when they were already dead and took some food.
Prosecutors say he came back yet again and set fire to Jessica's bedroom just minutes before Tammy's son found the bodies.
"That was put out immediately upon the first responders arriving," said Schenectady County District Attorney Robert Carney at a news conference Tuesday. "Brad McCormack came to the household and opened the door and saw that there was some disarray in the house and called police and when police came, the first responders were able to put out the fire which was contained to the mattress and bedding in Jessica's room."
Authorities say there was no forced entry. They would not comment on how the two were killed.
Police believe Rivenburgh tried to stage the scene to cover up, and that he set fire to his shirt and a paper with his name on it. A burning paper from a black car attracted the attention of both neighbors and police, who say it led them to find Rivenburgh in his car at his Oaklawn Avenue home without a shirt.
The district attorney said Rivenburgh even sent text messages to Jessica when he knew she was already dead.
"I can tell you that the first text message were the words to the effect of, 'do you want to hang out today,' and the second text message, 'are you still mad at me?'" said Carney.
Rivenburgh is expected to be arraigned on the new charges Wednesday morning.
