On April 6, 1968, two days after the assassination of Dr. Martin Luther King, Jr., and with riots raging across cities in the United States, the 17-year-old Hutton was traveling with Eldridge Cleaver and other BPP members in a car. The group confronted Oakland Police officers, then fled to an apartment building where they engaged in a 90-minute gun battle with the police. The standoff ended with Cleaver wounded and Hutton voluntarily surrendering. According to Cleaver, although Hutton had stripped down to his underwear and had his hands raised in the air to prove that he was unarmed, Oakland Police shot Hutton more than 12 times, killing him. Two police officers were also shot.
