Homicide detectives were investigating after a 73-year-old woman and her 50-year-old son were found dead in a Baldwin Park home Tuesday morning, but it's unclear whether there was any foul play, authorities said.
The incident occurred along the 3900 block of Kenmore Avenue, according to the Los Angeles County Sheriff's Department, which is assisting the Baldwin Park Police Department in the investigation.
After earlier saying the incident was reported around 5:25 a.m., sheriff's officials later said Baldwin Park police responded to the scene just before 4:45 a.m.
Other relatives who live in the home found the son unresponsive in the morning and called 911, authorities said.
Officials who responded to the scene found the man in one room and his mother in another. Both were unresponsive and pronounced dead at the scene, according to the Sheriff's Department.
Coroner's officials have yet to determine the victims' cause of death, but detectives said neither appeared to have suffered any traumatic injuries.
It is unclear, however, how the victims died.
"At this time investigators are not looking for a suspect," the sheriff's release states. "It is unknown at this juncture whether this tragic event is criminal in nature."
Officials are continuing to investigate the deaths and did not release additional details Tuesday.
Meanwhile, a neighbor who spoke anonymously off-camera told KTLA the female victim had been battling cancer and there were multiple police calls to the home recently.
"They said that the mom did have cancer and she was attending chemotherapy. She wasn’t going to be living too long," the neighbor said.
"I think the cops have been called probably about five or six times within the past few months," she said.
