New court documents claim Jared Remy threatened to kill the mother of his first child back in 2001.  That's added to brutal attacks upon other women in 2003 and '05. 

The son of the famous Red Sox announcer was fired from his job at Fenway in 2008 for alleged steroid abuse.  Remy is being held without bail for last Thursday's stabbing death of Jennifer Martel, the mother of his four-year-old daughter.
