who burned down the billboards in three billboards
Three Billboards Outside Ebbing, Missouri Discharged from the hospital, Dixon overhears the man who threatened Mildred bragging in a bar of an incident similar to Angela's murder. He notes the Idaho license plate number of the man's vehicle, then provokes a fight by scratching the man's face. At home later, he removes a sample of the man's DNA from under his fingernails. Meanwhile, Mildred goes on a date with James to thank him for the alibi. Charlie enters with his 19-year-old girlfriend Penelope and admits to burning the billboards while intoxicated. After accidentally causing James to leave, Mildred tells Charlie to treat Penelope well and leaves.
