The Los Angeles Police Protective League's rank and file chose Sandoz to fill a vacation position on the nine-member board, joining six white men and two white women, KNBC-TV, Los Angeles, reported. The union, founded in 1922, has an estimated 9,900 members.
Sandoz, a 20-year LAPD veteran, was selected during a special election to fill a vacant seat and will serve on the board until at least December 2014, the newspaper said.
"I am very pleased to be the president of the union at this time. I've known Jerretta for a long time and she was elected by a vote of her peers," said Tyler Izen, president of the Police Protective League. "She'll make a great director."
"We did it!!!!! I am grateful to God that I have the opportunity to serve this membership. Thank you all for your vote of confidence. Thank you for your support from the very beginning. I will work each day for you to protect you and fight for what is right. I am truly grateful," Sandoz said on her campaign's Facebook page.
