This is the second deadly shooting in Easton this year. Damien Robinson was killed in February at Eddie G's, a now-closed downtown bar. The investigation into his death is before a Northampton County grand jury.
Stratford and Robinson's deaths are two of the four unsolved homicides in Easton in the last 12 months, along with the shooting deaths of Ervin Holton and Paul Murray, which happened within days of each other on the city's South Side.
Stratford is the first female homicide victim in Easton since Christmas Eve 2010, when Kimiko Moon was shot and fatally wounded at her home in the city's Highlands section. Her killer, John McGlinchey III, pleaded guilty the following year.
