New York Police are searching for a 27-year-old Goldman Sachs analyst who disappeared over the weekend after attending a concert at a Brooklyn venue.

John Castic left The Brooklyn Mirage at about 3 a.m. after a performance by electronic music group Zeds Dead, Fox News said.

Castic’s friend Sara Kosteca wrote on Facebook that she’s anxious to find him, especially since they’re supposed to be together at her brother’s upcoming wedding.

“Any information would be greatly appreciated, as well as sharing this to anyone in NYC that might have seen him,” Kostecka said.

Castic is a graduate of DePaul University in Chicago and has been with Goldman Sachs for about a year.

According to Fox, a 27-year-old man was turned away from a concert at the same venue on June 11 because he appeared to be drinking. The man, Karl Clemente, was found dead in a nearby creek a week later.
