A man shot a former co-worker to death on Easter because he was offended by a joke told seven years ago, officials said Monday.
Stanford Douglas Jr., 29, was arrested on murder charges Sunday after a two-hour standoff with police. He allegedly shot William Berkeyheiser, 62, three times in the chest and shoulder on March 27 at Berkeyheiser's suburban home.
Prosecutor Diane Gibbons said Douglas told police he had been thinking about killing Berkeyheiser since 1998, when the two men worked at a Philadelphia nursing home and Berkeyheiser told a joke that offended Douglas.
The prosecutor would not say what the joke was.
Douglas hired a private investigator to find Berkeyheiser's house, Gibbons said.
