A teen and her Filipina mother were killed September 14 by the girl’s former boyfriend at their home in the borough of North Catasauqua, Pennsylvania, according to multiple news reports.

Rianna Glass, 16, and her mother, Rosalyn “Rose” Siobal Glass, 39, appeared to have been stabbed to death, caused by “sharp-force trauma.”

Rianna’s former boyfriend John Derwin Bradley, 17, was charged with double homicide and theft. After allegedly committing the crime, he and a companion, a 14-year-old girl, stole the mother’s car, drove too fast and crashed. They survived. A knife with the DNA of Bradley and the two women was found near his body. The relationship between him and the 14-year-old girl is not known. 

Northampton County District Attorney Terry Houck told  reporters Rianna was murdered just hours after she told the suspect she was dating another boy.
