John Francis (Jaco) Pastorius III, 35, an electric bassist who played with some of the leading musical groups of the age and whose brief career influenced jazz musicians worldwide, died Sept. 21 at a hospital in Fort Lauderdale, Fla.

Mr. Pastorius had been comatose since being beaten in a bar earlier this month, according to a hospital spokesman. In recent years, he had lived in the streets and had been treated for manic-depression and alcoholism.

His fatal beating may have been triggered by his trying to kick in the door of an after-hours club, police said. The club manager was arrested Friday on a charge of aggravated battery and released on $5,000 bond, police said.

Mr. Pastorius began his professional career playing in the milieu in which he died: Fort Lauderdale's drinking establishments. At his peak he toured with Weather Report, folk singer Joni Mitchell, the Herbie Hancock group, and the rock group, Blood, Sweat and Tears.

His rapid-fire fingering techniques and composing talent earned him a reputation in the late 1970s and early 1980s as one of the jazz world's top electric bass players. He also was nominated for three Grammys.

Mr. Pastorius was born in Pennsylvania. His family, who nicknamed him "Jocko," moved to Fort Lauderdale in 1959. After graduating from high school in 1969, Mr. Pastorius began appearing in nightclubs around south Florida with such bands as Wayne Cochran and the C.C. Riders and the Peter Graves Orchestra.

In the 1970s, Mr. Pastorius, a self-taught musician, joined a musical group called the Las Olas Brass, replacing the bass player. At that time, he disdained drugs and alcohol, saying they impaired his playing. Colleagues said he began to drink shortly after joining Weather Report, and the drinking became a habit. Critics in the early 1980s noted that Mr. Pastorius had become prone to wild mood swings and bizarre behavior.

In 1982, he pleaded guilty to resisting a police officer with violence after an argument with his wife. He was placed on probation, which he violated by riding drunk and naked on the hood of a pickup truck.

About 1984, he began spending most of his time in New York. Family and friends began hearing stories that he was always drunk, often slept in parks and smashed his guitars.

According to his brother Gregory, a doctor determined that Mr. Pastorius was a manic-depressive, with cyclic peaks in brain activity that gave him creative intensity. Alcohol made the disorder worse.

Mr. Pastorius and his former wife Ingrid divorced in 1985. He moved back to Fort Lauderdale, penniless, sometimes sleeping in a park.

In August 1987, a court declared him insolvent. On the evening of Sept. 11, he jumped onstage during a Carlos Santana performance and had to be removed. Then in the early morning hours of Sept. 12, he was beaten after being refused admission to a nightclub, police said. That establishment was one of many that ad banned him because of drunken, disruptive behavior.
