Homicide detectives were investigating the fatal shooting of three people and a related fire in the Antelope Valley early Saturday morning.
Emergency crews called to Tabler Avenue in Lancaster at 1:27 a.m. found a one-story home on fire, according to the Los Angeles County Sheriff and Fire Department.
Three men and a woman in their 20s inside the home suffered gunshot wounds, authorities said. Two of the victims were pronounced dead.
