The girlfriend of the man accused of killing a Penn Hills police officer and another man lied to police in her first interview with them.
Kashawna Jackson testified Wednesday that when she first spoke to investigators at 4:25 a.m. Dec. 7, 2009, she claimed Ronald Robinson had been with her for the entire previous day.
About two hours later, she admitted that she had been lying. She told police at the time that she didn't believe her boyfriend could have done what he was accused of.
Ms. Jackson was the first witness called on the fifth day of Robinson's trial in the slaying of Officer Michael Crawshaw, 32, and Danyal Morton, 40.
The prosecution alleges that Morton was killed because he owed Robinson $500 for cocaine.
Also testifying Wednesday were scientists from the Allegheny County medical examiner's office who talked about gunshot residue, DNA and firearms analysis.
Todd Luckasevic, the forensic pathologist who performed the autopsies on both victims, told the jury that Morton was shot four times in the chest and abdomen and that any one of those four wounds could have been fatal.
Officer Crawshaw, who was shot while sitting inside his patrol vehicle while responding to a 911 call from Morton at 201 Johnston Road, was shot twice -- once in the upper left arm and once in the head just below his left eye.
Dr. Luckasevic said the shot to the officer's head was "instantly fatal."
The case will resume this morning, and testimony could conclude by the end of the day.
If Robinson is found guilty of first-degree murder, the jury must then decide if he should be put to death. The defense has conceded he committed the crimes but argues that Robinson should be found guilty of second-degree murder, which would carry with it a term of life in prison with no chance for parole.
