I believe David worked for my father Claus N. Becker, Practical Builders, in Miami in the early 1960's.  Did he also go by the name of 'Jack', and have a brother or other relative in Miami who was also a plasterer?  I remember David working on store build-outs in Northside Shopping Center in north Miami, around 1959 to 1961.  I worked with my father at the time during summers and weekends, I was 9 years old.  I remember riding with him to other jobs where my father needed plastering work done. David had a 1956 Ford pickup, green, it was really a COOL truck so I thought at the time.  He was a very nice young guy and often worked Saturdays & Sundays if needed.  My condolences to your family, I hope I am not mistaken in identifying Mr. Reising as the man I remember.
