PORT JEFFERSON, N.Y. – A gruesome scene unfolded Sunday evening, Nov. 2 in the Long Island town of Port Jefferson, involving a Greek-American man who shot and killed his ex-girlfriend’s new boyfriend, and then killed himself.

Frank Panebianco and Jessica Kasten exited the Pour House Bar and Grill in Port Jefferson, ABC news reported, and headed to the parking lot when they were confronted by Michael Skiadas, Kasten’s ex-boyfriend. Apparently, the couple and Skiadas engaged in a screaming match, according to NBC News for NY, at which point a friend, Jack Schneider, attempted to calm Skiadas as the couple tried to drive away. To no avail, Skiadas went into his car, pulled out a shotgun, and hit Schneider with it.

Then, Skiadas approached the couple’s car and fired twice, killing Panebianco.  Skiadas then returned to his own car and killed himself.

Schneider did not suffer any serious injuries, and Kasten was not harmed.

Police continue to investigate the story.
