Ex-Marine Threatened to Kill White People in Mass Shooting, Feds Say

Kevin Shea,, May 13, 2024

A Hamilton man who was in the U.S. Marine Corps until last week has been charged with making threatening statements about killing white people in a shooting rampage, federal authorities announced Monday.

Joshua Cobb, 23, mentioned two possible attack locations, a Jersey Strong gym and an Aldi grocery store in Robbinsville, and said he had access to guns and the will to kill a lot of people, authorities allege.


“I want to cause mayhem on the white community. The reason i specifically want to target white people is because as a black male, they will NEVER understand my struggles. Same way I will never understand their struggles, but I don’t care to. I want to erase them. All of them really, but in this case as many as I possibly can,” Cobb posted on social media in December 2022, according to authorities.

He also wrote, “Tbh [to be honest] I hope I do progress into a serial killer.”

Cobb is charged with one count of transmitting a threat in interstate and foreign commerce. Investigators arrested him Friday night, May 10, and he’s currently incarcerated in the Monmouth County jail.


In court papers, federal investigators detail a damning list of posts Cobb allegedly wrote on social media, spoke to federal agents or had on his cellphone, which investigators seized last month.


In the December 2022 post in which he threatened white people Cobb also wrote that the attack would occur in New Jersey in 2023. He said the date would be, “close to an important holiday to their race. I have a location in mind already which I have frequented for the past year and I am certain nobody there is armed to be able to stop me from spraying them to the ground.”

Cobb joined the U.S. Marine Corps and attended basic training from June to October 2023, and reported for duty at a Marine base in Twentynine Palms, California in February.

Before that, from February to May 2023, Cobb allegedly posted – using the online moniker “ldayUsuffer” – critiques of federal gun laws, described torturing cats and divulged his own mental illness, and the struggles of being a young Black man from poverty.

“I promise I will make everyone feel my f—ing pain. My deep, sincere, raw, & sharp pain,” he wrote.
