PHILADELPHIA (AP) — A corrupt Philadelphia police officer testifying against former drug squad members acknowledges that marriage problems once led him to attempt suicide.
Defense lawyers note that Jeffrey Walker denied any prior mental-health treatment at his 2013 plea hearing.
They hope to discredit the 46-year-old Walker as he testifies for a third day in the racketeering trial of six former colleagues.
Walker says the elite squad members regularly perjured themselves in court, after stealing drugs and cash from suspects.
Walker says he was ostracized as he went through a messy divorce that led him to drink on the job and once lose his service weapon.
He says he had earlier attempted suicide in 2002.
Defense lawyers argue that the jury can't tell when Walker is lying and when he's telling the truth.
