TROY, N.Y. -- "It's crazy," said Troy resident Christina Holliday. "I mean, I remember the story many, many years ago when I went to school with Sharon and everybody heard. It was really sad."

Holliday was in middle school when her classmate, Sharon Crosier's mother was killed, a cold case Troy police never closed.

"Back in March of 1994, Rosemary Crosier was found murdered at an ARC facility in Troy that was located up on 2 Prout Avenue," said attorney Robert Becher. "And since that time, there's been an extensive and ongoing investigation with the City of Troy Police Department."

Monday, they announced two arrests: Scott Chaplin, 34, and George Mott, 42, both for second degree murder.

"As they say, the case takes you, you don't take the case," said Troy Police Captain Dan DeWolf. "Sometimes you hit road blocks for a little while and then things come up again. Sometimes people are reluctant to talk and then as time goes on, they feel more comfortable speaking to police."

Troy police credit the help of state police forensics and the FBI. Crosier family members say thanks to all who helped.

Rosemary Crosier's daughter, Bonnie, told YNN on the phone it's a blessing after 17 years and they're ready for it.

"Hope springs eternal," said Besher. "And perhaps there's never an end to those kinds of things."

"Everybody felt bad for her, you know," said Holliday. "It was a horrific thing to happen to her mom and to finally get a couple people, obviously, it's a lot of relief for the family."
