The man accused in Phoenix’s “Canal Killer” case may have his ancestors to blame for his 2015 arrest.
Records show forensic genealogy was key in leading police to Bryan Patrick Miller, a man now facing a death-penalty trial in the early 1990s slayings of Angela Brosso and Melanie Bernas.
Using a method with little precedent in the world of criminal justice, a California genealogist named Colleen Fitzpatrick handed police what would amount to a case-busting lead: the suspect’s last name.
“The name Miller came up in my analysis,” Fitzpatrick wrote in an email that she later forwarded to investigators.
Miller, a now-44-year-old father, was arrested within weeks of Fitzpatrick’s emails with police. His trial is scheduled to begin April 28.
Police had long held samples of crime-scene DNA they believed belonged to the killer, and Miller had remained in Phoenix for much of his adult life. But as investigators often bemoan, a DNA sample is useful only if you have a suspect's sample against which to compare it.
The first crime occurred in November 1992, when 22-year-old Angela Brosso failed to return home from a bike ride. Police soon would find her headless body near 25th Avenue and Cactus Road, and her head in the Arizona Canal several days later.
Ten months later, 17-year-old Melanie Bernas would face a chillingly similar fate. In September 1993, the high school student also had been out on a bike ride before her apparent abduction. Her body, which was discovered the next day, also was found in the canal.
After months of speculation, police confirmed what the community had feared. The two murders were connected by a single suspect’s DNA.
Over the years, it is likely officials had run the suspect’s DNA through databases such as CODIS, a national repository for the profiles of known criminal offenders. But because Miller had never been to prison, his DNA profile would not have been included in this database.
