LANCASTER A Lancaster man arrested in connection with the killing of a produce stand owner – and later cutting a gang investigator with a razor while in jail this summer – has pleaded guilty to all charges.

Circuit Court Judge Brooks Goldsmith sentenced Keith Tyrone Robinson, 20, to 45 years in prison, Sixth Circuit Solicitor Doug Barfield said.

Robinson pleaded guilty Monday to murder, attempted murder, armed robbery, first-degree burglary, possession of a weapon during the commission of a violent crime, and possession of a knife during the commission of a violent crime.

“He is required to do every day of the 45 years,” Barfield said.

Robinson had been held at the Lancaster County Detention Center since he was charged in June for fatally shooting 54-year-old Donald Morris in the head on South York Street in Lancaster.

Robinson’s armed robbery and burglary charges stem from an incident – five days before Morris was killed – when he broke into Morris’ house, robbed and pistol-whipped him, Barfield said.

Police have arrested four other men in connection with the robbery and assault against Morris. Jeremy L. Thomas, 23, was also charged with murder in Morris’ killing.

Robinson alleges that Thomas shot and killed Morris, Barfield said, but Robinson is responsible for Morris’ death under the state’s “hand of one is the hand of all” legal principle, in which courts have held that all who participate in a crime are as guilty as the person who actually committed the crime.

Barfield said he was unaware of any kind of prior relationship between Morris and the men who robbed him. He did say it was well known that Morris ran a produce stand and carried cash.

While in jail, Robinson was charged with attempted murder and possession of a knife when he cut investigator Fred Thompson, head of the Lancaster County Sheriff’s Office gang unit, on the neck with a razor.

Law enforcement officials were unable to determine how Robinson managed to hide the razor, Barfield said. The blade, which Robinson dropped to the floor after cutting Thompson, is consistent with other disposable razors jailors temporarily issue to inmates for shaving.

Court records show that charges against Robinson for purse snatching, driving without a license, two counts of hit and run, resisting arrest and unlawfully carrying a weapon were still pending at the time of Morris’ murder.
