 Rochester police say a woman and her adult son were found dead in an apartment yesterday in what authorities believe was a murder-suicide. Officers were called to the home on the city's north side for a welfare check. They found the bodies of a 54-year-old woman and her 30-year-old son. Police say they had been there for some time. Authorities say a handgun was located near the son's body, and they're not seeking anyone else in connection with the deaths. The names of the people who died haven't been released. The case remains under investigation.
