New details have emerged about Brian Weiss, who was murdered on Thursday during a business meeting at a NYC hotel. Weiss, who was shot in the head five times, was reportedly a top official in a Florida company that marketed dietary and health supplements.

According to the New York Times, the Better Business Bureau recorded over 4,000 complaints against FWM Laboratories, the company he worked for. Florida's attorney general apparently ordered the company to return over $34 million "for products they neither ordered nor wanted," the New York Times reports.


However, it is not known exactly what caused Gary Zalevsky to pull the trigger on Weiss.


We reported earlier that Zalevsky may have killed Weiss because of investment monies lost, according to Performance Marketing Insider. Zalevsky reported was facing pressure to repay investment money that had disappeared.


The investment money allegedly came from outside sources and it is believed that the pressure being applied to Zalevsky may have caused him to crack, leading to the killing of Weiss.


Thursday's incident saw two men killed in what the NYPD has described as a murder-suicide in the lobby of a Queens hotel.
Zalevsky, 47, and Weiss, 31, both from Florida, were sitting in a private room of the lobby at lunchtime with four other men, according to AP. The group of men appeared to be in their 40s.


There was allegedly an argument between the group of men. Zalevsky reportedly shot Weiss in the head five times, killing him immediately. He stepped back and looked on, and shot himself shortly afterwards.

The four other men were reportedly attempting to flee the scene but they have since been caught by authorities and detained. Three out of the four have now obtained lawyers, and are not speaking to the police, according to New York Times.
