EAST LONGMEADOW, Mass. (WWLP) – Michael Krol, one of the Dallas police officers ambushed and killed Thursday night, graduated from East Longmeadow High School in 1994.

Krol’s brother-in-law Brian Schoenbaechler told 22News Krol lived in East Longmeadow for a few years while his father worked for J.C. Penney. He spent most of his life in Michigan before moving to Texas in 2007.

Krol’s uncle, Jim Ehlke, said, “He wanted to do more, that’s just kind of how he was. He wanted to make everything better. He wanted to make things right and was really committed. That was probably the most frustrating thing for him, he couldn’t solve it all.”

The news from Dallas has rocked the East Longmeadow community, and friends of Krol told 22News they’re still in shock.

“I couldn’t believe someone I went to high school with, and that I was friends with, was a victim of murder and was a police officer in Dallas. It’s still tough to come up with in words,” said Anthony Gentile, a friend of Krol’s and now a public safety dispatcher.

Benjamin Nuzzolil, another high school friend of Krol’s, said, “He was one of those guys if you saw him at the barbecue or a house party, you would be in the car laughing about how funny it was to meet him. Nobody never had anything negative to say about him.”

Thursday night, Krol was one of the five officers killed when a sniper opened fire in Dallas; seven other officers and two civilians were wounded. “It’s just tough when someone you knew all through high school, is now no longer with us. It’s just an empty feeling,” said Gentile.

Before becoming a Dallas Police Officer, Krol worked for the Sheriff’s department in Wayne County Michigan. He was 40 years old.

Gentile said the news has forever changed his life; “Every time I send one of the police officers on a call, I’ll always have that in the back of my mind. It can happen anywhere. With that in the back of my mind, I will do my best to try to keep everyone safe.”

He added that the East Longmeadow Town Council is discussing a way to honor Krol’s memory.
