Mother, 52, speaks out after being shot defending daughter

The screams to 'call 911' haunt Suzanne Zaremba, as they were the last words she heard her 16-year-old daughter Charlotte say.

In the early hours of New Year's Day, Charlotte's 15-year-old classmate Sean Crizer broke into her room in Ellicott, Maryland, wearing a mask and shot her dead.

Altar boy Crizer injured her mother as she bravely tried to fight him off and he then turned the gun on himself.

Suzanne has now spoken out for the first time about the horrific attack and how she tried desperately to save her daughter's life.
