The Los Angeles County Board of Supervisors approved the payouts on Tuesday, including $900 ,000 in the case of a fatal shooting in Athens in 2009.
Darrick Collins, 36, a father of two, was fatally shot in the back by a deputy who at first mistook him for a robbery suspect, and then mistakenly thought he was reaching for a weapon. Collins was unarmed.
The other suits also involved 2009 incidents. In one, a woman injured during a fight with a deputy claimed she was arrested with excessive force and without probable cause. In the other, a man said he was injured during his arrest by deputies responding to reports of cockfighting and illegal drug use.
