Three people were killed and another victim was critically wounded early Wednesday in a shooting at a Fontana apartment that police said stemmed from a family's financial issues.
The 73-year-old shooting suspect surrendered to authorities at the property, police said, adding that the victims and gunman are family members. In a statement issued later Wednesday morning, police said the victims were killed "over a longstanding financial family issue."
Neighbors reported the sounds of six gunshots early Wednesday.
Two women and a man were found dead in the apartment. A fourth individual was hospitalized in critical condition.
The suspect was identified as Ali Zafar, of Escondido. The victims were identified as his nieces and nephews, police said.
Zafar was booked on suspicion of murder and attempted murder. Zafar told investigators that his family members owed him money, police told NBC4.
The gunman, who was holding the weapon when officers arrived, was arrested at the scene, police said.
