Toxicology reports that would indicate what, if any, substances were in Grant's system aren't expected to be available for weeks.

"Because we're still doing our investigation, we're very limited as to what we can talk about," Saratoga Springs Police Chief Chris Cole said. "All I can say is that we have a deceased person, and our job is to find out what happened."

Cole said foul play is not suspected in the case, but investigators are interested in learning more about what happened to Grant between the time he left the Church Street party and when he was recorded by the security cameras at the office building.

Police also want to know who provided Grant with alcohol because misdemeanor charges could be filed against that person.

"This is obviously the ultimate consequence of what we believe is an alcohol overdose, so if there's someone who's contributed to that, they should be held responsible," Saratoga County District Attorney Jim Murphy said.

Interviews with people who may have been at the party are ongoing, and police would not predict when the investigation will conclude.
