Florida authorities arrest teen accused of posting online threat to Heritage High School

Authorities in Florida have arrested a 14-year-old boy accused of posting a threat on Twitter that led to a lockdown at Heritage High School in Wake Forest on Wednesday.

The Pinellas County Sheriff’s Office arrested Marcus Xavier Dateno on Thursday afternoon. The teen is charged with making written threats to kill or do bodily injury through electronic communication.

Authorities released the boy’s name because the charge is a felony, said Sgt. Elizabeth M. Brady of the Pinellas County Sheriff’s Office.

Police think Dateno, a former Heritage Middle School student, tweeted Tuesday night that he was “shooting up Heritage.” He told deputies that he “thought it would be funny and did not believe anyone would take it seriously,” Brady said in a news release.

Police locked down Heritage High School on Wednesday morning and also put precautions in place at nearby Heritage middle and elementary schools.

Dateno, who lives in Crystal Beach, Fla., was arrested at the high school he attends, Palm Harbor University High in Palm Harbor, Fla.

The investigation continues in the case.
