Two people believed to be in their teens were found dead Friday at a Lancaster home, and authorities said they appeared to have "lacerations and stab wounds."
The deaths were reported about 8 a.m. in the 45000 block of Century Circle, according to the Los Angeles County Sheriff's Department.
Paramedics went to the location on a report of a possible natural gas leak, according to the Los Angeles County Fire Department. However, sheriff's Lt. Brandon Dean told reporters at the scene that the pair -- possibly a teenage boy and girl --- may have been stabbed to death, and apparently did not die as a result of a natural gas leak.
"Detectives have learned that the deceased male and female both appeared to be suffering from lacerations and stab wounds," said Deputy Eric Ortiz.
