Police reveal that separate collisions reported in May and July resulted in the deaths of a car passenger and two pedestrians.

San Jose Police said they suspect that the man officers fatally shot on Sunday had killed his child and called 911 to get into a deadly confrontation with police.

The witness had just finished a basketball camp he teaches and was on the nearby pickleball courts at Cataldi Park when he saw police officers responding. Mateusz Dzierbun, of Fremont, stabbed his 9-year-old son to death on Sunday at the park.
