There's a lot of evidence for suicide being socially contagious, particularly through communications to the general public which will inevitably find their way to people who in that moment are particularly vulnerable. Newspapers publishing suicides causes an untick in subsequent suicides. Newspapers publicizing murder-suicides even causes an increase in murder-suicides. Publicized information about suicides by train increase the rate of suicides by trains.

It is therefore a beat practice to generally avoid mention suicide, because mentioning suicide means prompting people to think about suicide and in some cases that means prompting people to consider suicide. This is known as the Werther effect, you can look that up if you'd like to know more.
