SACRAMENTO (CBS13) – A high school sophomore was attacked at school, beaten so badly he was rushed to the hospital, but the suspects aren’t classmates and they should never have been on campus.

The victim didn’t know what was about to happen in an attack that his family says he never saw coming.

Students started snapping photos as police rushed to Inderkum High School on Tuesday.

According to his family, the teen was punched, kicked and knocked to the ground until he was unconscious.

One of the suspects is a teenage girl, 18. The other, Dapree Oshea Johnson-Stowers, 19, was charged with felony assault. Both were booked into the Sacramento County Jail.

“Right then and there some other guy started taking off on him and they just started fighting and after they were fighting for a while some girl just jumped in and was hitting him,” a student told CBS13.

“It was just a bad situation,” said another.

The 15-year-old was rushed to the hospital.

According to the victim’s family, the fight started when a junior at the school approached him about some negative Facebook posts. Then, the victim’s family says a former student snuck onto campus and jumped the teen.

Students watched in disbelief.

“He was knocked out,” one said. “He couldn’t move.”

Inderkum was on lockdown for about 15 minutes until police had their suspects. The school district confirmed they are not students and had no business being on campus.

Many students were surprised that the attack wasn’t just between guys, but that a girl got involved.

“The girl was hitting him and I guess he didn’t want to hit her back,” one said.

Now his family is fighting for answers, wanting to know how two people who didn’t belong there ended up on campus with no one noticing.

The victim’s brother says his brother never put anything mean on Facebook that they know of. He was reportedly conscious and doing better Tuesday night.

The high school added an extra security presence after what happened, but they still couldn’t tell me how these two people who shouldn’t have been on campus ended up there.
