COLORADO SPRINGS — The person accused of opening fire in an L.G.B.T.Q. nightclub in Colorado, in a rampage that killed five people and injured at least 17 others, was formally charged on Tuesday with 305 criminal counts, including 10 counts of first-degree murder, 86 of attempted murder and 48 of bias-motivated crimes.

The police say that the suspect, Anderson Lee Aldrich, 22, walked through the front door of Club Q in Colorado Springs near midnight on Nov. 19, wearing body armor and carrying an assault-style rifle, and immediately started firing. The assailant was tackled and beaten into submission by two unarmed club patrons and was held until the police arrived.

The hearing on Tuesday was the first time the defendant appeared in court in person since the shooting. Wearing bright yellow jail scrubs, the defendant was upright and attentive,  and appeared to have healed significantly since a video court appearance in the days immediately after the shooting. At that time, the suspect seemed to be slumped over, with eyes swollen shut and a bruised face, and struggled just to speak.

The defendant is being held without bond at the El Paso County jail. After the charges were filed on Tuesday, the judge overseeing the case, Michael McHenry, set a preliminary hearing in the case for February. At the request of prosecutors, the judge agreed to unseal the arrest affidavit by Wednesday.

No clear motive for the shooting has emerged publicly. But the inclusion of charges of bias-motivated crimes, commonly known as hate crimes, by prosecutors suggests that they believe the attack was motivated specifically by antipathy toward the L.G.B.T.Q. community.

Speaking to reporters after the hearing, District Attorney Michael Allen declined to discuss details of the investigation, but said that his office felt confident that it had evidence to prove the bias-motivated crime charges.
