Sean Armstead, 36, is the NYPD cop who shot his wife’s lover and then himself Sunday
Investigators probing a suspected murder-suicide in upstate New York believe the gunman was a jealous NYPD cop who gunned down a love rival outside a Buffalo Wild Wings before turning the weapon on himself.
DailyMail.com has learned that off-duty officer Sean Armstead tailed his 35-year-old spouse, Alexandra Vanderheyden, and her 20-year-old suspected lover Edward Wilkins to a La Quinta hotel on the opposite side of a parking lot to the Buffalo Wild Wings.
The pair jumped in their car to flee but the veteran cop sped after them in his grey Dodge Charger and slammed into them right outside the bar.
A guest at the neighboring Super 8 hotel said she heard the smash and saw two men emerging from the cars, one chasing the other.
After a volley of gunshots, the younger man slumped to the floor in a parking spot.
‘I heard eight shots. The cop shot him multiple times until he was dead,’ said the shaken guest, who would only give her first name, Jennifer.
‘Then the cop, in shooting himself, landed on top of the body. They were both on top of one another in the same spot in a pool of blood.
‘The woman was screaming and running in and out of Buffalo Wild Wings. She was crying hysterically, it looked like she was going to pass out.
‘People were still there cleaning up the blood at 4:30am.’
