Bobby Lowe, Logan's neighbor, testified that on September 27, while walking his dog, he observed a vehicle parked across the street with its engine running and Logan walking to his parked automobile. As Lowe approached Logan to speak with him, the other vehicle pulled up. Lowe heard two loud noises and saw Logan fly backwards. Defendant exited the passenger side of the vehicle, approached Logan with a gun-like object in his hand, which he pointed at the fallen Logan. Lowe stared at defendant for four or five seconds, standing three or four feet away, then turned and ran. While running, he heard another loud noise and heard the vehicle drive away. In 1972, he picked out defendant's photograph and again, in 1976, he identified defendant as Logan's shooter for police. As a result of witnessing the shooting, Lowe was forced to quit his job and was relocated. He received money from the State during both trials. Lowe had incurred many debts, which he paid in part with money received from the State.
Louis Almeida, a career criminal who had grown up in the same neighborhood as defendant, testified for the State. In March of 1975, while driving through Ohio on their way to "kill somebody" for $10,000 in Pennsylvania, he and Joe Neri were stopped by Ohio police and arrested for possession of weapons and a silencer. Almeida provided police with information about his various criminal activities, including armed robberies, vehicle thefts, and bombings. Later, he reported details of Logan's murder identifying himself as the driver and defendant as the shooter. In exchange, Almeida was given immunity from prosecution for Logan's murder.
According to Almeida, in August of 1972, defendant discussed his plan to kill Logan and gave him two license plate numbers and Logan's home and work addresses, writing "Death to Billy" on the same piece of paper. Almeida then trailed Logan to learn his habits and schedule.
On the evening of September 27, 1972, defendant, armed with a shotgun and a .45 caliber handgun, was driven by Almeida to Logan's block, where he parked. Almeida observed a man walking a dog. At 11:15 p.m., he saw Logan. Almeida drove the automobile near Logan. Defendant called to Logan. Logan walked toward them. Defendant shot him twice with a 12-gauge shotgun. Logan "flew back" and began crawling and yelling for a doctor. Defendant stepped half-way out of the car, but "shut the door on the car and [said], let's go, he's gone"...
