BOSTON — Prosecutors poorly handled assault allegations against Red Sox broadcaster Jerry Remy’s son just before he allegedly killed his girlfriend, according to an independent review released Wednesday.

Jared Remy was arrested Aug. 13 after he allegedly pushed Jennifer Martell into a mirror.

He was released on his own recognizance Aug. 14 and allegedly stabbed Martel to death at their apartment the next day. He has pleaded not guilty.

The review found that Middlesex County prosecutors did not adequately consider Remy’s history of domestic violence and the details of the alleged Aug. 13 assault.

It says they placed too much weight on Martel’s decision not to seek an extension of a restraining order against him.

The couple had a daughter, then 4 years old.

“We believe this deficiency contributed to the decision on August 14, 2013 to request that Remy be released with only bail warning and a no abuse order,” an executive summary of the report said.
