BALTIMORE COUNTY, MD – More than four decades after 59-year-old Samuel Allen was fatally shot in his Liberty Road home, Baltimore County detectives have identified a suspect in the long-unsolved homicide thanks to a breakthrough in DNA technology.

PHOENIX — A 35-year-old man has been arrested in connection to a homicide investigation from 2010, Phoenix police said. Officials said Walter Zimmer was found dead at a bus stop near 51st Avenue and Thomas Road on September 5, 2010, just after 6 a.m.

Seeking to stop a rapist, veteran DNA detective CeCe Moore found herself fighting a battle among the trees—family trees, that is. And as a result of her meticulous mystery-solving acumen, Utah can claim the bragging rights as the place where, for the first time, genetic genealogy was employed to solve an active case.

Phoenix police say a man who was questioned by investigators this week confessed to a murder at a west Phoenix bus stop that happened 15 years ago.
