SAGINAW, Texas (AP) — A toxicology report shows that a 25-year-old man fatally shot by a North Texas police officer after attacking police and others in a residential neighborhood had amphetamine and methamphetamine in his system.

Michael Dale Brown's toxicology report was released Wednesday by the Tarrant County medical examiner's office. Police have said Brown destroyed a front door, vandalized several cars and fought several people on Jan. 30. He was hit twice by stun guns deployed by officers before he was fatally shot by a Saginaw police officer.

His autopsy report says a small plastic bag containing "clear crystal-like substance" was found in his clothes.

Saginaw police spokesman Sgt. Damon Ing tells the Fort Worth Star-Telegram ( ) the toxicology results are a piece of the ongoing criminal investigation into what happened that night.
