MA - Daniel Rodriguez, 37, killed in Lynn home invasion, 7 Jan 1994

[PastTense]

A man who had spent 21 years behind bars for a murder he says he did not commit was released from prison Monday after a Massachusetts judge threw out his sentence, ruling that the prosecution's case was flawed.

Superior Court Judge David Lowy officially vacated a life sentence imposed on Angel Echavarria for the 1994 shooting death of Daniel Rodriguez in Lynn.
