Sean Armstead, an off-duty NYPD cop, followed his wife and a man (Edward Wilkins) he thought she was having an affair with on Sunday night.

According to law enforcement officials, an NYPD officer trailed his wife and her young new boyfriend to a hotel, where he ruthlessly shot the man before killing himself in a horrible love triangle gone terribly wrong.

Reportedly, crazed off-duty Policeman Sean Armstead, 36, trailed wife Alexandra Vanderheyden, 35, and her 20-year-old boyfriend, Edward Wilkins, to a La Quinta Inn in upstate Wallkill at 10:30 p.m. Sunday.

So, who is Edward Wilkins?

Who Is Edward Wilkins?  Alexandra Vanderheyden Boyfriend

Edward Wilkins of Wurtsobo was said to be the young boyfriend of Alexandra Vanderheyden, wife off-duty officer.

According to reports, Vanderheyden informed detectives that she suspects Armstead monitored her using her smartphone.

Similarly, the two got into their car to run, but the senior officer chased them down in his grey Dodge Charger and smashed into them just outside the pub.

A Super 8 hotel visitor reported she heard the crash and saw two guys emerge from the automobiles, one pursuing the other.

Furthermore, after Edward was murdered, his family gathered at his house in Mamakating, New York, but when reached by DailyMail.com, they declined to respond.
