What happened to Sabrina Hatheway?

Sabrina was last heard from on Dec. 20, 2014.

In the weeks following, her ex-boyfriend Kevin Crozier, with the help of two friends, tried burning down his grandmother's home on Dixfield Road in Worcester in a futile attempt to collect insurance money.

Three months later, in March 2015, Crozier and his co-conspirators are in court facing multiple charges, including arson.

But none of the three men can provide -- or are willing to provide -- an answer on Sabrina's whereabouts.
