Richard Carl Robison was born in
Wayne County, Michigan, in November 1925. He had met his fiancée, Shirley Fulton, in the mid-1940s while both attended college. The couple wed in 1947 and had four children: Richard Jr. (b. 1948); Gary (b. 1951); Randall (b. 1955); and Susan (b. 1960). Robison had founded and operated a small advertisement agency named R. C. Robison & Associates in the mid-1950s. The firm strategized advertisement campaigns for businesses with the
Detroit region; he also worked as a commercial artist, executive and publisher for
Impresario magazine, which focused on cultural issues such as
the arts, theatricals and music and was also based within his one-story
Southfield office. The markedly wealthy family owned a private
Learjet, and lived in the affluent Detroit suburb of Lathrup Village. By 1968, Richard Jr. attended
Eastern Michigan University, Gary was a student at
Southfield-Lathrup High School, Randall was a
middle school student, and Susan—described as a "pony mad" child—a
first grade student. The family regularly attended
church services, and neither parent drank, smoked or gambled. The family planned to spend three weeks of their vacation at Summerset, the seasonal log-and-stone holiday cottage they had purchased in the 1950s for $15,000. The five-room cottage itself was situated at the end of a long private driveway within a heavily-wooded area and which at one section runs alongside a 100-foot
bluff close to the Lake Michigan shoreline. The vacation began on Sunday, June 16, with the family traveling in two cars to the destination. They were accompanied by several traveling companions, who would stay in their own rented holiday homes. These individuals included friends of the Robison boys, some business acquaintances, and personal friends of Richard Sr. and Shirley. Among those to know about the vacation and the location of the Robisons' secluded holiday home were several senior employees of
Impresario magazine. On June 23, one of the Robisons' traveling companions, 18-year-old Norman James Bliss (the son of the caretaker of Blisswood Resort and a close friend of Richard Jr.), was killed in a motorcycling accident while returning to Good Hart from nearby
Cross Village, reportedly while
intoxicated. An autopsy revealed his cause of death to be
cerebral hemorrhage. The accident occurred sometime after 1:30 a.m., and the Robison family did not learn of the accident until that evening. Upon receipt of this news, Richard Sr. paid personal condolences to Bliss's parents at their Good Hart holiday home, offering to pay for the teenager's grave marker and flowers or a wreath. He also explained the family would be unable to attend the funeral as they were due to fly from
Pellston Regional Airport to
Kentucky, then
Florida, with view to purchasing
real estate and would "not be back [to their cottage] for a couple of weeks." He added the earliest date they would likely return would be July 15.
June 25, 1968 On the morning of June 25, Richard Robison Sr. telephoned his personal banker at the
National Bank of Detroit, Frank Joity, to discuss business pertaining to an expected recent deposit to his account of $200,000, only to be informed that the deposit had not been made, of financial irregularities within his business account within recent weeks, and that his current business balance was just $15,000. These revelations infuriated Robison, who telephoned his receptionist, demanding to speak to a senior employee of his named Joseph Scolaro III—the only employee of his with direct access to company accounts The final confirmed sighting of the Robisons occurred at approximately 4:30 p.m. on June 25, when two individuals tasked to trim trees within the grounds of Summerset left the property. ==Murders==
