A Dallas County grand jury returned indictments Wednesday against two teens in connection with the delivery of marijuana-laced muffins to the Lake Highlands High School teachers' lounge last month.
Former Bishop Lynch High School student Ian McConnell Walker and former Lake Highlands student Joseph Robert Tellini, both 18, each face five counts of assault of a public servant.
Officials said 18 school staff members were hospitalized May 16 after snacking on the drugged pastries, though none were seriously injured.
At a news conference May 26, Mr. Walker called the incident "juvenile and stupid" and expressed regret in the incident. Mr. Tellini has not made a public statement.
Mr. Walker's attorney Tim Menchu would only say he is "disappointed" by Wednesday's indictment.
As a result of the indictments, new warrants have been issued for the teens' arrest.
