Convoluted sentence 

I read this sentence multiple times and cannot parse it: 

"After speaking with officers involved with the case in 1986, Frazier called the "accident" description inaccurate,[8] and he and others said that then-chief John Polio ordered Bishop released to her mother[42][22]—allegedly a political supporter of the chief[22] as a member of the Braintree town meeting,[7] and who, they said, demanded to meet with Polio personally after the arrest[43][22]—instead of being charged for the shooting.[8][36]"

It is too long and the final phrase: " —instead of being charged for the shooting.[8][36]", makes little sense in the light of the rest of the sentence. Can someone familiar with the story straighten it out?
