My seat was just below the nose-bleed area of the Forum, the lights were still on, when all of a sudden I heard loud screams coming from the floor. I saw people trying to disperse in all directions, while a bare-chested guy remained all by himself right in the middle of the floor. But let the Los Angeles Times continue the story:
Los Angeles, California: July 29, 1986, page 2:
A man stabbed himself repeatedly in the chest and stomach with a hunting knife in what police said appeared to be an attempt to impress a girl at a Forum rock concert. Inglewood police and security guards wrested the weapon from the hand of Jonathan Moreland, 38, and administered first aid until he could be turned over to paramedics, who took him to UCLA Medical Center for treatment. He was later reported in satisfactory condition. Bare chested and wearing a cowboy hat and jeans amid the mostly teen-age crowd that had come to hear The Cure, a British band, Moreland told police he wanted to impress a girl named Andrea. A suicide note was found in his truck, parked outside the arena.
The concert started with a delay, of course, but the evening had been already ruined.
