A cop accidentally shot the elderly father of an alleged drug dealer in The Bronx while raiding the suspect’s home early this morning, police said.

Police officer Andrew McCormack, whose own father was killed in the line of duty, inadvertently discharged his service weapon during the 7 a.m. search on Evergreen Avenue and hit the 76-year-old man, authorities said. More after the jump…

(NY POST)–Authorities – including seven narcotics officers and Emergency Service Unit contingent – swarmed the Bronx property to execute a search warrant seeking the man’s 41-year-old alleged drug dealer son Alberto Colon.

Police, who uncovered heroin inside the raided fourth floor apartment, made several undercover buys from the suspect during a lengthy investigation, sources said.

The suspect’s injured father was taken to Jacobi Medical Center and is expected to survive, sources said.

Colon – who has at least a dozen arrests – left in cuffs, police said.

McCormack, a 13-year veteran, is the son of an Emergency Service Unit officer who was killed during a Bronx standoff with an emotionally disturbed man in 1983.

Police officer Joseph McCormack, a 15-year veteran, was killed by Salvatore Ferrara, who fired as he escaped the Mulford Avenue building’s backdoor. The unhinged suspect’s bullet ricocheted off a tree and pierced McCormack’s heart.

The valiant veteran fired, as did another officer whose bullets killed the deranged man. McCormack left behind a wife and three kids. Andrew and another brother, also named Joseph, would go on to become cops.

Joseph McCormack’s widow, Susan McCormack, founded Survivors of the Shield, a group for survivors of slain police officers. When Andrew McCormack became a police officer in 1998, she supported her sons’ becoming cops.

“You always worry about your kids,” she said then. “But this is what they wanted to do and I’m behind them.”
