A man who spent decades in prison for fatally stabbing his wife was released after being deemed too old to pose a threat — only to be convicted this week of a nearly identical crime.

It took jurors in Maine less than an hour to find Albert Flick, 77, guilty in the 2018 murder of a homeless mother, Kimberly Dobbie, who was stabbed at least 11 times while her twin sons watched.

That crime is eerily similar to the slaying that sent Flick to jail for 25 years in 1979 — slashing his then-wife Sandra Flick 14 times in front of her daughter.
