Of the 10 NYPD officer suicides in 2019, eight have happened since June. The cluster rattled the department, with leaders trying to come up with a way to tell the rank and file that it's OK to ask for help

Over the past five years, the NYPD has averaged between four and five suicides a year, Police Commissioner James O'Neill said in June at a news conference called after the department surpassed its average.
