SAN ANTONIO (AP) -

A San Antonio student has been indicted on a charge of making a terroristic threat after being accused of using social media to allude to an attack on his school.
    
Matthew Murray, 17, was indicted Tuesday on the third-degree felony that could result in a sentence of up to 10 years in prison.
    
Murray and another Alamo Heights High School student were arrested after police were alerted in August to a Facebook exchange between the two referencing the 1999 Columbine High School massacre in Colorado.
    
Charges though were dropped Thursday on an identical charge against the other student because of lack of evidence.
    
Attorney Bob Behrens, who represents Murray, says neither teen was being serious.
    
Attorneys say both students are now homeschooled.
