The restaurant in Maine that was targeted in a mass shooting last night posted a message Thursday saying that "my heart is crushed" and "in a split second your world gets turn upside down for no good reason." 

Schemengees Bar & Grill wrote the comments on Facebook as a massive manhunt is underway to find 40-year-old Robert Card of Bowdoin, who has been identified by police as a person of interest in the shootings in Lewiston. Eighteen people have been killed at Schemengees and a bowling alley identified by police as Sparetime Recreation and in signage as Just-In-Time Recreation, Maine Gov. Janet Mills said.

"My heart is crushed. I am at a loss for words. In a split second your world gets turn upside down for no good reason," Schemengees Bar & Grill said in the post. "We lost great people in this community. How can we make any sense of this. Sending out prayers to everyone." 

Schemengees had been advertising an industry night on Wednesday with bar and restaurant workers getting 25% off their bills.

The mayor of the nearby city of Auburn, Jason Levesque, told NBC's "Today" show on Thursday that the bowling alley was hosting a youth night.

According to an internal Maine Information and Analysis Center bulletin obtained by Fox News, Card is a firearms instructor and has military experience.
