PITTSBURGH — A jury that already determined a city man will die in prison for killing his next-door neighbors, two sisters of an Iowa state lawmaker, now must determine how he’ll die, the convicted killer’s defense attorney told the jury Tuesday.

“You’ve decided where Allen Wade will die. He’ll die in prison,” defense attorney Lisa Phillips told the Allegheny County jury in her opening statement of the penalty phase of the 45-year-old man’s trial. “Will he die slowly, day by day ... until an act of God takes him? Or will he die quickly, in an execution chamber by lethal injection?”

The same panel of seven women and five men on Monday convicted Wade of first-degree murder, burglary and other crimes for the Feb. 6, 2014 killings of Susan Wolfe, 44, and Sarah Wolfe, 38. They were the sisters of Democratic Iowa state Rep. Mary Wolfe, who has attended the trial.

Wade shot the women in head after accosting them as they returned home, separately, from work that night. Wade did that apparently to steal a bank card he used to withdraw $600 from an automatic teller machine hours later — money he needed to pay his rent and avoid eviction, prosecutors said.

The jury must eventually determine whether Wade deserves to die by lethal injection or spend life in prison without parole.
