CHICAGO — The police officer who shot and killed teenager Quintonio LeGrier on the day after Christmas will sue LeGrier’s estate.

Officer Robert Rialmo answered a domestic disturbance call in West Garfield Park and wound up shooting LeGrier and a neighbor, he says, because LeGrier attacked him.

Rialmo’s attorney Joel Brodsky confirmed for WGN-TV this morning that he’ll file a civil suit against LeGrier’s estate in a couple of weeks, citing emotional distress and assault.

LeGrier’s family says there was no justification for shooting 18-year-old LeGrier in the back four times.
