-The message references Harvard Westlake High School and shows a shotgun with multiple rounds of ammunition lying on a surface. It reads, “When you’re a bully victim & a coward, your options are suicide, or revenge.”

-The message also tags current NFL players Mike Pouncey and Richie Incognito. 

–Incognito and Pouncey allegedly bullied Martin while they were all members of the Miami Dolphins. That incident became national news and resulted in an NFL investigation after Martin went public with the allegations. 

-Martin said in a message announcing his retirement from football in 2015 that he once attempted suicide during his NFL playing career. 

– Harvard Westlake High School closed Friday as a precaution. LAPD said that the closure was because of actions by a “former student of the preparatory school [who] apparently used Instagram to say he wanted to seek revenge for alleged bullying he underwent when he attended one of the school.”

-In a statement obtained by the Los Angeles Times, Harvard Westlake said: “The safety of our students, faculty, and staff is always our primary concern. So, out of an abundance of caution, we made the decision to close school today,” the email read. “The school’s private security team is working with the Los Angeles Police Department, which is present on both campuses. With these precautions in place, we believe there is no imminent threat to our campuses or our school community.”

–Pouncy is still on the Miami Dolphins while Incognito plays for the Buffalo Bills.
