Lawyer who attacked his own family was haunted by brother’s death on 9/11

The Manhattan lawyer who attacked his wife and three children with a bat and knife in their Connecticut home had been depressed and wracked with grief before his rampage, according to a report.

Christopher Andrews was distraught by the death of his mother two weeks before he beat and stabbed his family Tuesday – and also was still haunted by the 9/11 death of his brother at the World Trade Center, the Connecticut Post reported.

The brother, Michael, was working on the 105th floor in one of the two towers that were destroyed in the terror attack.

Andrews, 51, who had an office on Lexington Avenue, recently experienced mood swings and was taking prescription sleep medication, sources told the paper.

Police are still investigating what led Andrews, described by friends as “squeaky clean,” to unleash his fury on wife, Kathleen, 12- and 15-year-old sons and 13-year-old daughter at 22 Mount Laurel Road.

It could take several weeks before an autopsy can determine whether medication played a role in his attack.

Fairfield police officer Sean Fenton encountered Andrews standing in his driveway, clutching a bloody knife. The cop pointed his gun at him and ordered him to drop the knife, but Andrews ignored the order and moved forward, police sources told the paper.

Fenton stepped back but was blocked by a snow bank before again ordering Andrews to drop the weapon. After the man again refused, Fenton opened fire.
