A 59-year-old man was killed by a relative inside his Hayward home, police said.

Officers went to the house on the 27000 block of Eucalyptus Court before 8 a.m. Tuesday after someone reported a disturbance. Before they could get there, a person inside the home called 911 to say a man, Albert Williams, had been shot multiple times.

Police found three residents and a neighbor in addition to the wounded Williams, who was pronounced dead shortly after officers arrived. It was Hayward’s fourth homicide this year.

The alleged shooter, a family member of the victim, was arrested without incident, said homicide Sgt. Ryan Cantrell. Police were withholding his name and other details until a charging decision by the Alameda County district attorney’s office.
