Glen Cove Police Department spokesman Det.  Lt. John Nagle said officers responded to a shooting call at The Mansion in Glen Cove shortly after 5 p.m. Sunday and said the three injured were taken to a hospital for treatment.  None of the injuries were life-threatening, he said. 
On Monday, Nagle said, “We’re looking at all the leads in the investigation, right now. And we’re hoping to make strides in identifying the shooter.” 
However, he said, no arrests have been made. 
Nagle said hotel management, including the property owner, as well as guests who attended the rally were all “cooperative” with investigators — and said police believe at this time there was one assailant, a man.  He said police have not yet found the gun used in the shooting. 
“Since we haven’t found the gun, I can’t speculate on the gun or the caliber of the gun that was used,” Nagle said. 
There were about 150-200 people at a “Big Fendi Celebrity Pool Party” at The Mansion, Nagle said Sunday.  The pool party was advertised online, officials said.  
The hotel was evacuated and cordoned off Sunday night.  Several officers searched the front of the area, while the K-9 unit was active. 
Glen Cove Mayor Pamela Panzenbeck was at the scene Sunday night and said she was shaken by the incident. 
“This was not something we ever expected.  We go to high school reunions and weddings and fundraisers and all kinds of things here,” she said.  “These were not Glen Cove people who were here today, so we have to look at how they got here and how this happened.” 
Panzenbeck said the permitting process will change.  
“No permits will be issued for this in the future, I promise,” Panzenbeck said. 
He did not specify what he meant by “something like that” or how he knew the attendees were not from Glen Cove. 
No one at the hotel was available for comment. 
Describing the incident, Nagle said Sunday that “there was some kind of scuffle” and that one of the security guards working the event tried to escort a person out of the party and shots were fired — injuring them.  The other two victims were partygoers, he said. 
The shooting happened inside the mansion near the lobby, he said.  
“We hope to quickly close this case,” Nagle said Monday, adding that he hopes to have updates on a suspect “soon.” 
The Mansion at Glen Cove, a Georgian brick mansion surrounded by a 55-acre estate, was built in 1910 for Standard Oil executive John Teele Pratt and his wife Ruth Baker Pratt, the first woman elected to Congress from New York . 
It is one of the estates that made up Long Island’s Gold Coast. 
The Mansion at Glen Cove has also been featured in many films, including Alfred Hitchcock’s 1959 classic ‘North by Northwest’ and ‘Sabrina’ starring Humphrey Bogart, Audrey Hepburn and William Holden.  In 1967, it became one of the first convention center hotels in the country, according to its website.
