INFORMATION ABOUT A MOTIVE There is no known connection between the victim and the shooter, police said.Formella said Nadeau previously worked at the Sky Meadow Country Club for about a year, though the nature of his employment status when he left was not known. "It looked like a target, that he was going right for this person," said witness Tom Bartelson. "I feel terrible for him."Bartelson said Nadeau was saying things during the shooting."He just came out and said, 'The children are safe,' and, 'Free Palestine,'" Bartelson said.Despite reports of “free Palestine” comments made by the suspect, investigators said he also made several other statements. "At this point, the evidence leads us to believe it is more likely that Mr. Nadeau was simply trying to make a number of statements to create chaos in the moment," Formella said.Formella said it is believed there is no hate motive in connection with this case. "At this point, we don’t have any evidence to indicate this was a hate-based act," Formella said.PATRONS CREDITED FOR ACTIONS AFTER SHOOTINGFormella said the shooting, while tragic, could have been a much worse situation. He credited the action of patrons after the shooting."I want to extend my heartfelt gratitude to the patrons in the restaurant who acted selflessly and quickly with more care for their fellow citizens than for themselves to help keep this a contained event and minimized this tragedy as much as they could," Formella said.INTERVIEW WITH VICTIM'S MOTHERA woman who spoke to WMUR's sister station WCVB on Saturday night at the Nashua Police Department identified herself as DeCesare's mother. Evie O'Rourke said her son jumped in front of his wife and daughter to protect them."He kicked the door open, and Rob just went right for him and protected his family," O'Rourke said. "We don't know any information more about it other than they have arrested him, but boy, is he going to be missed. He's just a great guy."Law enforcement officers from more than a dozen communities in New Hampshire and Massachusetts responded to the scene when calls about the shooting came in at about 7:30 p.m. In audio obtained by News 9 from Broadcastify.com, dispatchers can be heard alerting police that someone had been shot in the face.>> Download the free WMUR app to get updates on the go: Apple | Google Play <<"It's so shocking that we just can't believe it. We think everybody's lying. This can't have happened," O'Rourke said. "They were just enjoying a meal at their country club, and in comes the guy, shot the maître d', and it was right in front of him. And I guess he died right there."DeCesare lived at Sky Meadow and was dining there with his family when the shooting occurred. >> Subscribe to WMUR's YouTube channel <<"His thought was to take care of his family," O'Rourke said. "And his daughter's getting married in six weeks, so it’s going to be very tough."
