BAKERSFIELD, Calif. -- Friends and family members gathered Monday afternoon to remember the life of a man who died last week in a southwest Bakersfield parking lot.

Co-workers drove street sweeper trucks to Greenlawn Cemetery Monday in memory of 61-year old Donald Dinesen.

Dinesen's body was discovered near his running sweeper truck last Tuesday in front of Cone's Health Food on Wible road.

Friends said they'll miss their co-worker of more than two decades.

At first officials believed Dinesen had been the victim of foul play, but a coroner's investigation revealed he had suffered a heart attack and died of natural causes.
