A man leapt to his death after climbing out the tenth-story window of a Midtown high-rise Monday. According to police, the unnamed 30-year-old man jumped from the 10th story of 250 Park Avenue, near the corner of East 46th Street, just before 1 p.m. He was pronounced dead at the scene.

The man was reportedly a mail room employee at Satterlee Stephens LLP, a law firm operating out of the building, and had openly told his colleagues he planned to jump in the moments leading up to his death, the NY Post reports.

“I saw him on Friday … He was quiet and on his phone,” a FedEx employee who often made deliveries to the man's floor told the tabloid. “It looked like he was stressed as hell.”

If someone you know exhibits warning signs of suicide: do not leave the person alone; remove any firearms, alcohol, drugs or sharp objects that could be used in a suicide attempt; and call the U.S. National Suicide Prevention Lifeline at 800-273-TALK (8255) or take the person to an emergency room or seek help from a medical or mental health professional.
