An NYPD officer killed himself in Westchester County this morning, Yonkers Police said.

This marks the eighth NYPD suicide this year and the sixth since June. NYPD Chief of Patrol Terence Monahan also confirmed the news during an appearance on the Brian Lehrer Show on Tuesday morning.

CNN reports, "The 35-year-old was a seven-year veteran who temporarily was assigned to a detail surrounding Yankee Stadium. The officer left a note behind, the law enforcement official said. He was off-duty at the time, two law enforcement sources told CNN."

Sources tell the Daily News that the unnamed officer shot himself in his home. His fiance was reportedly in the house when he killed himself around 3:30 a.m.

Update, 12:15 p.m.: The Yonkers Police Department says it's investigating the death, nothing, "Around 3AM this morning, Yonkers Police members responded to a location on Shoreview Drive on a report of a suicide. Thereat officers located the victim unresponsive and apparently deceased; the victim was subsequently pronounced at scene. Preliminary investigation has yielded no indications of foul play, and the manner of death appears self-inflicted in an apparent suicide."

In June, Police Commissioner James O'Neill urged officers to reach out for help, "This cannot be allowed to continue. Cops spend so much of their days assisting others. But before we can help the people we serve, it is imperative that we first help ourselves. There is no shame in seeking assistance from the many resources available, both inside and outside the department. Accepting help is never a sign of weakness — in fact, it’s a sign of great strength. Please, connect yourself or your friends and colleagues to the assistance that is so close by. We must take care of each other. We must address this issue — now — because it will not go away on its own. We must speak out. And we must end this crisis, together."

However, officers may feel they face challenges when even considering seeking help. A retired detective told the NY Times, "The job will tell you they’re here to look out for you, but the No. 1 rule is the job is there to protect the job. You go in there and say you’re depressed or whatever, they modify you. They take your guns."

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.
