Officials say the 49-year-old lieutenant -- who was off-duty at the time -- entered the woman’s home and began shooting at the couple around 11:20 p.m. Sunday night, before fleeing the scene, NJ.com reported. The motive of the alleged attack is unclear.

"She ran out of that house, went to next-door neighbor banging on the door, yelling she had been shot," Thomas Verrone, a retired Passaic County Sheriff’s Officer who lives in the area, told the website. "But it was late at night so no one answered."
