Dr. Emmett Charles Velten Jr., a 69-year-old psychologist who had lived in Phoenix for about 11 years, was murdered on April 24, 2011. Surveillance shows him entering his condominium complex near 2300 North Central Avenue at about 8:10 a.m. accompanied by an unidentified younger man; that was the last time Velten was seen alive.

About three hours later Velten was found in a hallway with a severe head injury. He was able to give police a brief description of his attacker and said he had picked the young man up at a homeless shelter. The suspect was described as a white male about 23 years old, roughly 5 feet 9 inches and 145 pounds. Video captured the man leaving alone carrying a tan mail-type bag and later driving away in Velten’s vehicle; the car was abandoned near North 35th Avenue and West Glendale. Investigators recovered a bloody footprint at the scene, while other items, including an empty beer bottle, produced no conclusive DNA or fingerprint matches.

No arrests have been announced and the murder remains unsolved. Does anyone have information about the younger man seen with Velten or the vehicle found near North 35th Avenue and West Glendale?
