PITTSBURGH (AP) — The defense attorney for a Pittsburgh man accused of having killed two sisters of an Iowa state lawmaker says the investigation of him was a "sham." Attorney Lisa Middleman spoke to an Allegheny County jury for nearly two hours Wednesday at the close of 45-year-old Allen Wade's murder trial. Police and prosecutors say Wade killed 44-year-old Susan Wolfe and 38-year-old Sarah Wolfe after they returned from work the in February 2014. They were sisters of Democratic Iowa state Rep. Mary Wolfe Prosecutors cited surveillance video and DNA evidence. Middleman says police purposely ignored evidence that pointed to other suspects and calls the DNA link to her client faulty. Jury deliberations are expected to begin after the prosecution's closing arguments and the judge's instructions to the panel.
