Donald Eugene Webb (born Donald Eugene Perkins; July 14, 1931 – December 30, 1999)[1][2] was an American career criminal wanted for attempted burglary and the murder of police chief Gregory Adams in the small town of Saxonburg, Pennsylvania on December 4, 1980.

[13] Webb was identified by the FBI as an associate of the Patriarca crime family, who made a living robbing banks, jewelry stores, and high-end hotels up and down the East Coast.

[14] In 1979, Webb and two accomplices allegedly burgled suburban Albany homes while posing as sewer and water inspectors.

Lach is from Cranston, Rhode Island[8] and was believed to be involved with a Massachusetts-based gang responsible for a number of jewel thefts from residences and businesses in the 1960s and 1970s, as well as having ties to organized crime in New England and South Florida.

(See below)[8][17] Lach was subsequently wanted by the FBI for interstate flight from justice; he was captured in South Miami, Florida in May 1982.

[18] In February 1986, he was convicted by a federal jury of conspiracy to transport stolen property interstate,[19] and of driving under the influence and parole violation in June 1996.

On December 4, 1980, Gregory B. Adams, a 31-year-old police chief of Saxonburg, Pennsylvania, and nine-year veteran of law enforcement, made a routine traffic stop in the parking lot of Agway Feed Store[11] on Butler Street.

[22] The man believed to be Donald Eugene Webb got out of the car and fought with Adams,[9] disarming him and pistol-whipping him with his own revolver.

[13] Witnesses heard fired shots; four "pop" noises, presumably from a semiautomatic .25-caliber Colt pistol,[8] and a "boom" from Adams' revolver.

[13] By another account, Adams was shot twice in the chest,[22] one bullet collapsing a lung and another tearing through the bottom of his heart.

[22] A .25-caliber Colt pistol, O-type blood (Webb's blood type), and a New Jersey driver's license bearing the name Stanley John Portas, an alias of Webb and the name of his wife Lillian's late prior husband, were among the evidence found at the murder scene.

[24] Adams' revolver was later found approximately 7 miles (11 km) away along Cornplanter Road in Winfield Township, Pennsylvania.

[13] Significant amounts of O-type blood were found under the steering wheel, suggesting that Webb was wounded by gunfire in the struggle with Adams.

[23] Webb had strong ties to Fall River and New Bedford, Massachusetts,[8] where the last confirmed sighting of him was made by an anonymous tipster in July 1981.

The letter suggested he might surrender to authorities,[24] but only if he could talk directly to John Walsh, host of the TV show America's Most Wanted.

[10][25] In April 2005, an unidentified man in Detroit was found using Webb's name, age and Social Security number.

[27] Key investigators, including the FBI special agent assigned to finding Webb, believed he was still alive.

FBI investigators had announced that in 2016 they had discovered a secret room hidden behind a closet in the basement of Lillian Webb's home in North Dartmouth, Massachusetts.

He had been treated for four weeks in Tobey Hospital in Wareham, Massachusetts, under an assumed name for a compound fracture to his leg in 1980 after the murder.
