Munzur moved to Waukesha 11 years ago and opened up Cafe De Arts on West Saint Paul.
"I have several messages on Facebook of people praying for us. I appreciate that. It's so sad," he said.
One day after the attack, Munzur said he continues to monitor social media.
Turkey has faced a string of terrorist attacks over the past year as it confronts threats from both the Islamic state and Kurdish militants fighting a war with the Turkish state in the southeast.
"Over there, right now, every day something is happening," Munzur said.
That's why Munzur has decided not to send his 6-year-old daughter Claire and 13-year-old son Justin to visit family in Istanbul right now.
"My wife's side of the family is asking us to send them for the summer but now we are more worried. We think we are going to hold off for a couple of years until everything settles down," Munzur said.
