PHILADELPHIA (AP) — A Philadelphia abortion provider won’t testify or call witnesses at his capital murder trial, leaving jurors to weigh five weeks of prosecution evidence.

Dr. Kermit Gosnell, 72, is charged with killing four babies allegedly born alive at a clinic that authorities have described as filthy. He is also charged in the 2009 overdose death of a 41-year-old refugee who died months after coming to the U.S.
