Earlier this week, a teen in Fresno, California, was arrested by police after a search of his family's house, which turned up a cache of guns and ammunition. What prompted the search? The day before, the teen had posted lyrics from an Eminem track called “I'm Back.”

In the track, Eminem raps, “I take seven kids from Columbine, stand ’em all in a line / Add an AK-47, a revolver, a nine / A MAC-11 and it oughtta solve the problem of mine / And that’s a whole school of bullies shot up all at one time / I’m just like Shady and just as crazy as the world was over this whole Y2K thing.”

But confusing the matter, in a press conference, the police mistook the teen's post for lyrics from Eminem's track “Rap God,” which simply use the lines, “I take seven kids from Columbine, stand ’em all in a line / Add an AK-47, a revolver, a nine.”

Initially, the police thought that the teen's longer Instagram post used words that the teen made up himself.

“I want to read that posting to you,” Fresno Police Chief Jerry Dyer said in the press conference, “because part of the posting that was placed on Instagram is part of a rap song called 'Rap God' by Eminem, but you'll see that this 15-year-old student added to that post some of his own words which is what caused the concern.” The police chief later retracted his statement about the Instagram post being from “Rap God.”

However, the police maintained that the Instagram post was evidence of making terrorist threats, which is a felony, and of disrupting school activity, according to the Fresno Bee. The comments under the Instagram post added to the police's concern, they said, because another teen allegedly wrote, “Bring me with man. I got some stuff [to] settle.”

The 15-year-old San Joaquin Memorial High student then apparently replied, “Ill text you when,” and added, “I got a couple idiots’ blocks I could knock off,” Dyer said.

The school's vice principal initially contacted the police about the teen's Instagram post. The Fresno police did not respond to Ars' request for comment.

Dyer said at the press conference that the teen claimed that he did not make the posts and suggested that his computer might have been hacked. The teen also allegedly told the police that he took the Instagram post down. The police seized the teen's phone and iPad. The teen's lawyer, Linden Lindahl, also did not return Ars' request for comment.

Police officers came to the boy's house on Monday and searched it with the teen's father's consent. They found a replica AK-47 Airsoft rifle in plain sight and returned later that evening with a warrant to search the house more extensively. There, police say they found a handgun, a .357 Magnum revolver, a 12-gauge shotgun, ammunition, and a bulletproof vest stashed away in the subfloor of a closet in the father's bedroom, the Fresno Bee reports. The paper added that, “the boy’s father could also face charges for 'negligent storage' of firearms and because he has an active restraining order against him and is forbidden from owning firearms.”

On Tuesday, Both San Joaquin Memorial High and St. Anthony's Catholic School, which the teen previously attended, canceled school due to the perceived threat, and the teen was arrested. Both the schools reopened on Wednesday.

In a news conference, Fresno Police Chief Jerry Dyer painted a picture of a teen who was a loner and bullied. The teen's mom passed away earlier in the year from an illness and he broke up with his girlfriend recently, the police chief said.

“These are really all of the things we look for in individuals that historically have been involved in incidents like Columbine,” Dyer said in a press conference. “So we’re very fortunate that this was brought to our attention. We have every reason to believe that he was reaching out for help.…The weapons were present. The ammunition was present. Perhaps even the mindset was present to carry out those threats.”

The teen's defense attorney refuted the claims to the Fresno Bee, saying that his client was neither depressed nor bullied, and that the boy had only had a small argument with his girlfriend recently.
