The son of a New Windsor woman gunned down by an ex-employee is suing several Orange County departments he claims mishandled an arrest that might have saved his mother.The family is seeking damages from Orange County, its probation department, the DA?s office and the sheriff?s department. In 2005, Christian Schaare?s mother, 48-year-old Joanne O?Brien was fatally shot by Victor Piazza, a convicted sex offender. Piazza, 55, stormed into the Verla International Perfume Factory and gunned down three people, including O?Brien, who later died.Schaare and his attorney, Ravi Batra, say Piazza targeted O?Brien because her grand jury testimony helped convict him of child pornography possession. He was sentenced to 10 years probation. Piazza then publicly threatened O?Brien in front of law enforcement. Three days before she was shot, sheriffs allegedly caught Piazza in possession of pornography, a parole violation. Batra says they should have arrested him, but they instead told Piazza they?d come back Monday. Piazza drove to the factory on Monday and went on a shooting spree. He later turned the gun on himself. The family says they hope the lawsuit changes protocol for handling parole violations.
