Chief Greg Adams


Details: Career criminal Donald Eugene Webb is wanted for the murder of thirty-one-year-old Saxonburg, Pennsylvania police chief Gregory "Greg" Adams. He is currently on the FBI's Ten Most Wanted list.
Saxonburg is a small town twenty-five miles north of Pittsburgh. Crime was virtually non-existent there. At around 2:50pm on the afternoon of December 4, 1980, sixteen-year-old Tiger Freehling heard the sounds of gunfire and a fight coming from outside his bedroom; he believed the sounds were coming from the parking lot of a nearby store. He told his mother Midge about the sounds, so she went outside to investigate. In some nearby bushes, she found Greg, severely injured. He told her that he had been shot and asked her to summon help. When she asked him who attacked him, he told her that he did not know the assailant. Looking up, she saw a white car driving away from the scene. She tried to comfort him, but he asked her to pray for him because he did not think he would make it.
Within three minutes, paramedics arrived at the scene. Greg was taken to the hospital; he had been shot twice and beaten severely. Sadly, he died of his injuries soon after. He left behind his wife Mary Ann, two young sons Greg Jr. and Ben, and a grieving community who demanded answers. Within hours, State Police investigators were on the scene of the shooting, a parking lot of the Agway Feed Store. It was determined that Greg had been shot during a routine traffic stop; the killer's driver's license was found at the scene. It is believed that it came out of Greg's hand when he was shot. The license belonged to a man named Stanley John Portas. Also found at the scene was the gun used to kill Greg. It had been emptied and was void of any serial numbers. As a result, they were unable to trace it to anyone.
The driver's license belonging to Portas turned out to be the key piece of evidence. It had a date of birth and an address in New Jersey. Police determined that he had died in 1948 and was buried in a cemetery in Dartmouth, Massachusetts. They also discovered that he had a widow. When she was contacted, she told them that she had since re-married. Her new husband was Donald Eugene Webb; he had completely taken on Portas's identity. Webb was a member of the Fall River Gang, a group that robbed stores and homes throughout the East Coast.
Police believe that on the day before the shooting, Webb and an accomplice had visited a Saxonburg jewelry store. Webb asked to look at some rings. During this time, he and the accomplice cased the store, determining where the jewelry was kept, how it was protected, the location of the alarm systems, and the number of employees that were working.
The next day, Greg was working his final shift before taking his annual vacation. At approximately 1:45pm, he left the police station to begin his patrol. He was last seen by witnesses near the intersection of Water Street and Butler Street. He, along with the other witnesses, noticed a white Mercury Cougar not stop at a stop sign. This caught his attention immediately. He made a u-turn on Water Street and followed the vehicle. He lost sight of it after making the turn but then spotted it attempting to turn around in the Agaway parking lot. He then blocked it from exiting the parking lot.
Most police officers are trained to approach a traffic stop from the rear. However, due to the positioning of the cars, Greg could not make that type of stop. He instead had to approach from the front. As a result, he was in a bad position. As he approached Webb, he asked for his driver's license. He then looked at the information to see if it matched Webb. It is believed that at that point, Webb pulled out his gun and fired at Greg. Based on blood trails at the scene, the two get involved in an intense struggle on the ground. At one point, Greg was able to shoot his gun and apparently hit Webb, as Webb's blood was also found at the scene. Eventually, they ended up in the bushes next to the Freeling home. Webb, realizing Greg's gun is empty, then beat him over the head with it. He then fled the scene. Seventeen days later, his car was found in Warwick, Rhode Island. Blood linked to him was found in it. It is believed that he has since returned to southern New England.
On December 8, 1980, Greg was laid to rest at a funeral attended by several hundred officers from all over the state. The town of Saxonburg has since erected a monument to memorialize Greg's life and death. On it, the town's residents have inscribed a "thank you" to a man who gave his life protecting their community.
Extra Notes:

  • This case first aired on Special #1 on January 20, 1987 in a FBI fugitive roll call. It was covered in more detail in a full segment on the December 13, 1989 episode.
  • This case was also profiled on America’s Most Wanted.

Results: Solved. After Webb eluded capture for more than three decades, he was removed from the FBI's Ten Most Wanted list on March 31, 2007. He was on the list longer than any other fugitive before Victor Gerena, who surpassed his record in 2010.
In November 2016, the FBI discovered a secret room off of a closet in the home of Webb's eighty-two-year-old former wife Lillian in North Dartmouth, Massachusetts. They suspected that he may have hidden there after the murder. A cane was also found there, which was believed to have been used by him after he was shot in the leg by Greg. Faced with the possibility of jail time for harboring a fugitive, she decided in July 2017 to confess to investigators about what happened to Webb.
Lillian explained that after Greg's murder, Webb was treated for his leg injury at Tobey Hospital in Wareham, under the alias "John". He spent one month there. After his release, he lived in a hidden room in the basement of her New Bedford home. In 1997, she bought the Dartmouth home, where Webb lived in the basement and also hid in the secret room there. He suffered multiple strokes over the years and died in December 1999 at the age of sixty-eight. She then placed him in a green Tupperware storage container and buried him in the backyard. On July 13, 2017, human remains were found there. On July 14, the remains were identified as Webb's.
For Lillian's cooperation, she received immunity from prosecution. The case is now considered closed.
