A Turkish school shooter used imagery referencing a 2014 U.S. mass killer, according to police statements reported by Turkish authorities. The incident highlights ongoing concerns about the international influence of past mass violence events on subsequent attacks.

Separately, authorities in New York arrested three teenagers who allegedly planned a copycat shooting targeting a middle school, according to police reports. The suspects reportedly referenced previous mass violence incidents including Sandy Hook and Columbine in their planning.

The arrests came after authorities discovered the alleged plot during their investigation. One of the arrested individuals was described as being obsessed with previous school shooting incidents, according to law enforcement sources.

These incidents reflect broader patterns that security experts have documented regarding the influence of previous mass violence events on subsequent plots and attacks. Authorities continue to monitor online activity and communications that may indicate planning for similar incidents.

The investigations remain ongoing in both cases, with authorities working to determine the full scope of the alleged plans and any additional participants or influences involved in the plotting.
