Jim Springer, Jr., 29, was born in Connecticut. His family moved to Cache Valley, Utah when Jim Jr. was 9. He graduated from Sky View High School in Smithfield, Utah in 1990.

Jim loved the mountains and would go camping whenever he got the chance. Jim and his Dad enjoyed fishing together & the joke between them was "a dollar for the first fish." Jim almost always won the dollar!

Jim's only sibling, a sister Donna married Jeff and started a family. Jim loved being an uncle to her 3 children (Josh, Kyle, and Marissa). He was jokingly known as "awesome Uncle Jim" after finally breaking the piñata for them one Easter.

In August 1999, Jim married Jenni; they were in love and ready to start a family. The couple had their first child, James D. Springer III in June 2000. Jim Jr. loved being a dad. The couple brought their second child, Devin, into the world in September 2001.

Jim Jr. was offered several opportunities by AMF. He turned down a New York offer because the attacks of 9/11 had occurred and he feared for the safety of his family. He also turned down an offer to manage in Salt Lake City because of the coming of the Olympics and security concerns. Finally, Jim accepted an offer to become an assistant manager in Littleton, CO which he felt would be a safe place for his family.

Jim Jr. reported for work at the Broadway Bowl in Littleton on December 3, 2001. After only 7 weeks on the job on January 27, 2002, Jim called his wife and said "I'm done closing. We're waiting for Erin's ride (Erin Golla was snack bar manager of the bowling alley) then I'll give Bobby a ride (Bobby Zajac worked at AMF lanes in Highlands Ranch but frequently hung out with friends at Broadway Bowl) and then I'll be home. That was the last conversation between the couple. Jenni, worried when Jim failed to come home, called friends who went to the Broadway Bowl to find police and Jim's car in the parking lot. Jim, Bobby and Erin lay dead inside. They had been shot to death. The safe was open and emptied.

Helen Towers, 69, was born in Deer Trail, Colorado. She lived in Littleton. Helen was passionate about justice. She worked for Marty Miller, the popular District Attorney in Arapahoe County for 18 years, then worked as a legal assistant for 20 years after that. Helen, a beautiful dancer, loved to ballroom dance. She danced often at Senior Centers in the area. Another of her interests was poker. Her daughter, Julie, says she was a very accomplished player. In March 2000, Helen told her daughter that frightening notes had been left on her car, a four-year-old, bright red Monte Carlo. On April 1, Helen's neighbors called Julie to say newspapers were piling up at her mother's house which had been dark for several days and that they found a fresh red rose in the snow at the front door the day they called. Police and firemen were called to the house and entered through an unlocked kitchen window. Helen's body was found in the bathtub of the Littleton home she had lived in for forty years. There was no water in the tub, no evidence of foul play and no toxic substances in Helen's body. Julie says all the lights had been unplugged and the telephone was left off the hook. The threatening notes were found in Helen's purse. Later, another ballroom dancer across town began receiving similar notes. This person also drove a red sports car. Helen's death was eerily similar to the 1999 case of Rebecca Bartee, an Arapahoe County Attorney whose body was also found in the bathtub in her apartment with no evidence of foul play. The Arapahoe County Coroner lists Helen's cause of death as "Undetermined." If you think you have information about this death, please contact the Littleton Police Department, 303-795-3890.

Robert Zajac (Zy-us), 23, played Little League baseball as he grew up, but there is no doubt that his favorite sport was bowling.

He would often hold down two jobs, working at AMF Lanes in Highlands Ranch and driving for Domino's. But most of his friends were at Broadway Bowl in Littleton according to his dad, Roy Zajac. It was difficult for Robert after he split up with his long-time girl friend. But he was getting his life back together and had a job lined up with CDOT. Robert enjoyed the mountains and liked to go up to his grandmother's cabin north of Deckers. On Jan. 27, 2002, in the office of Broadway Bowl, three people were gunned down in an apparent robbery: Jim Springer, 29, Erin Golla, 26, and Robert.

Morton Rosenfeld was born in Chicago in 1935. He graduated from the University of Wisconsin in 1957 with a B.S. in English. There he met his future wife, Judith. Morton then studied acting in New York City, appearing in some off-Broadway plays.

Morton was drafted into the U.S. Army in 1958 and served in the Public Information Office at Fort Bragg, NC. Morton and Judith were married in August, 1958, when she returned from a year of post-graduate study in France. To this union was born a daughter, Stephanie, in 1960 and a son, David, in 1964.

Morton attended the NYU School of Filmmaking and worked in New York City in film editing until 1970. Then a cousin of his told him of an opening teaching filmmaking at the University of Utah. He applied for, and got, the job. Morton loved Utah, enjoying skiing and hiking especially. He also enjoyed all sorts of music, from jazz to classical. He was very popular with his students.

In May of 1979, he bought a VW Beetle and headed for the film festival in Telluride, CO. At first he stayed with his father-in-law in Boulder, but through a friend in Salt Lake City, he arranged to stay at a condominium in Windcliff Estates, near Estes Park.

Morton had been in Colorado only ten days when his badly beaten body was found on May 19, 1979 by Tom Rack, the owner of the condominium, on returning to Windcliff Estates. There were no signs of forced entry. Many people were distraught when they learned of Morton's death. A cinematographer friend tried to film the condo where Morton met his death, but was chased off by Douglas and Ron Buser, the sons of one of the principal developers of Windcliff Estates.

Judith believes that the killer is known, or highly suspected, by the Larimer County Sheriff's Office, but that office informed her that all physical evidence of the crime was accidentally destroyed in l983 during their transition to computers. The Rosenfeld family wants the killer(s) brought to justice.
