A 59-year-old doorman at an Upper East Side building was killed this morning after he fell through a pane glass window while shoveling snow.

Police say Miguel Angel Gonzalez, 59, was shoveling snow in front of 333 East 93rd Street near First Avenue at around 9:30 a.m. today when he lost his balance, toppling into the window. He suffered lacerations to his neck and face, and was taken to Metropolitan Hospital where he was pronounced dead.

Mayor Bill de Blasio addressed Gonzalez's death at a press conference on blizzard preparation this morning. "It's a reminder to be very careful when you're shoveling," he said. "If you're not up to shoveling, don't shovel. Take breaks—all of those common sense rules. We don't know what happened in this case, just want to remind people to take it seriously."

Gonzalez is the first reported NYC death from today's storm.
