(CBS) WALTHAM, Mass. - Red Sox broadcaster Jerry Remy released a statement Saturday saying he is plagued by "disgust and remorse" over the arrest of his son, Jared Remy, who is charged with fatally stabbing his girlfriend.

"My thoughts and prayers go out to Jenn Martel and her family. Words cannot describe my wife's and my grief," the statement read. "Son or not, I am at a loss for words in articulating my disgust and remorse over this senseless and tragic act. We are heartbroken."

Jared Remy, 34, pleaded not guilty Friday to murder and assault and battery charges in the death of 27-year-old Jennifer Martel.

Police were called to a home in the Windsor Village apartment complex in Waltham, Mass. around 9 p.m. Thursday on a report of a person stabbed. The couple's 4-year-old daughter was in the apartment at the time of the alleged attack but she was reportedly unharmed.

Remy is being held without bail.

Middlesex District Attorney Marian Ryan said Jared Remy was previously arrested on August 13 for assault and battery on Martel. He was later released on his own recognizance and there was no active restraining order between the two at the time of Martel's death.

According to CBS Boston NewsRadio 1030, Jared Remy has 13 criminal complaints against him since 1998. Six of those are reportedly for assault and battery.

Court documents obtained by CBS Boston reportedly show Remy was charged with assault and battery on three other women in 2005, 2003 and 1998.

He once worked for the Red Sox in security but was fired in 2008 in a steroid investigation, according to a report by the Boston Globe.

The mother of Jennifer Martel says her daughter felt trapped in her relationship with Remy.

"She was afraid, she was afraid to leave," Patty Martel told CBS Boston on Friday. "But then she was telling me on our last conversation on Wednesday, she said, 'I'm planning my escape.'"
