A man who killed three people and injured nine more in a shooting at a Planned Parenthood clinic in Colorado Springs says he's been forcibly medicated while being held at the state psychiatric hospital.

Robert Lewis Dear Jr. made the claim Tuesday while entering a courtroom for a hearing, but it wasn't immediately clear if it was true.

The Gazette reports that Dear's attorney said in court that the forced medication issue was addressed at a previously unannounced hearing last week in Pueblo, home of the Colorado Mental Health Institute. District Attorney Dan May confirmed there was a hearing, but he also didn't disclose its result.

Dear has been held at the hospital since May when a judge ruled he wasn't fit to continue his legal proceedings.
