Deputies and first responders investigate the home in Lancaster, California where 19-year-old Miguel Sandoval allegedly, murdered four people on Saturday, Nov 16, before setting the home on fire and fleeing. He was arrested hours later 

Sandoval was taken into custody by the LASD, however he has not yet been charged, and charges against him are due to be brought to the district attorney on Monday.  
Detectives said they believe the home where the shootings took place held a party earlier that evening. However, it is unclear if Sandoval was a guest or showed up uninvited later in the evening, explaining that Sandoval was ‘known to’ the victims, although it is not known in what capacity. 
The 16-year-old girl who survived the mass shooting reportedly called 911 shortly before 1:30am on the night of the shooting, after Sandoval allegedly opened fire on guests inside. 
The four deceased victims were each found with several gunshot wounds, with the fourth dying in hospital hours later after being raced from the scene by paramedics. Investigators believe the victims were in bed when the shooting took place. Firefighters eventually brought the blaze under control around 2am.
