A North Whitehall Township man pleaded not guilty Jan. 18 to two charges of criminal homicide and one charge of theft related to the Sept. 14, 2023, killing of a North Catasauqua woman and her teenage daughter.

John Derwin Bradley, 18, was charged Sept. 19, 2023, with the stabbing death of Rosalyn Siobal Glass, 39, and her 16-year-old daughter, Rianna Lynn Glass, a junior at Northampton Area High School. Both women were found dead in their home at 1106 Railroad St., North Catasauqua.

It is alleged that Bradley, who was 17 at the time of the incident, and Rianna Glass had previously been romantically involved, and their relationship reportedly ended in August 2023.

Bradley is also charged with the theft of Rosalyn Glass’ Nissan Murano. It is alleged he used the vehicle to flee the scene before crashing it in the area of Spring Valley Road in Upper Saucon Township. There was also a 14-year-old female passenger in the vehicle, identified as S.K.Q., when it crashed.

Upper Saucon Township police reportedly responded to the single- vehicle crash just before 6 a.m. Sept. 14, 2023, and found Bradley and S.K.Q. ejected from the vehicle.

An investigation reportedly connected the vehicle to Rosalyn Glass and revealed a Smith and Wesson HRT fixed-blade, double-edged knife with a red-brown stain and a white long-sleeved T-shirt with a similar stain near Bradley.

North Catasauqua officers reportedly received no response to calls to the Railroad Street residence on file for the vehicle. They then responded to a report of an unresponsive woman at the residence and found Rosalyn and Rianna Glass.

Video footage from neighbors allegedly show a man matching Bradley’s description entering the Railroad Street home 9:11 p.m. Sept. 13, 2023. A female matching the appearance of S.K.Q. was reportedly also recorded walking around the front of the residence and entering just after 2:30 a.m. Sept. 14, 2023.

The videos are said to show both the male and female leaving the rear of the residence around 3:30 a.m. Sept. 14, 2023. Seven minutes later, a vehicle matching Rosalyn Glass’ Murano was reportedly seen traveling west on Arch Street.

According to Northampton County District Attorney Terry Houck, a search warrant was executed for DNA swabs from Bradley Sept. 15, 2023. Forensic analysis reportedly confirmed the knife contained DNA from Bradley and Rosalyn and Rianna Glass. Bradley’s DNA was also reportedly found in a red-brown stain on the Railroad Street home’s kitchen floor.

The Sept. 16, 2023, autopsies confirmed Rosalyn Glass died from multiple stab wounds, and Rianna Glass died from neck compression and stab wounds, according to the coroner’s report.

Bradley, appearing for his formal arraignment and pretrial conference before the Honorable Judge John Morganelli, was represented by Northampton County Public Defender Molly Heidorn. Bradley previously waived his preliminary hearing Nov. 9.

The Press reached out to Heidorn Jan. 19 for further comment, but none was received by press time.
