Calvin Ferguson, 42, was killed on March 31, 1985, in Los Angeles. He worked in the vacuum truck business in the Signal Hill area and was one of the victims in a shooting spree carried out that day by Arthur Hans Halvorsen, a self-employed contractor from Long Beach. The attack sequence included three separate incidents in which four men were shot; Vicente Perez was also killed and two others were wounded.

Investigators described the attacks as random and unprovoked. Halvorsen’s background as presented at trial included severe mental health problems, bipolar disorder, heavy alcohol use and financial stress. He was arrested, tried on multiple counts including first-degree murder, found guilty and the jury determined a firearm had been used. One murder count ultimately resulted in life without parole; another count was later retried and resulted in a death sentence.

Does anyone have memories of Calvin’s work in Signal Hill or information about the victims from that day?
