As Nassau County police try to piece together an apparent murder-suicide in Hicksville, the victim?s brother is questioning whether authorities did enough to save his sister.

Police say Linda Ehrilchman was shot to death Wednesday at Botto Brothers Plumbing and Heating store, where she worked. According to police, Ehrilchman?s ex-boyfriend, Craig Saboski, stormed into the store, chased her with the gun and then shot her before committing suicide. Authorities say the only other people in the store were the owners, but they barricaded themselves in an office.

Ehrilchman?s brother claims his sister was stalked by Saboski for months before the incident. He says she had an order of protection against Saboski and had even called his probation officer to put an end to his stalking.
