One of three people accused of providing guns to the killer of Deputy Sheriff Kyle Pagerly has pleaded guilty.

Sandra Keim, 50, of Kempton, was sentenced in Berks County court Wednesday to three years probation on charges of illegal sale or transfer of firearms.

Two other people charged in the case -- Maurice Connor and Jared Engleman -- are due in court next month. Connor, a retired police officer from Cherry Hill, N.J., is the father of Matthew Connor, the man accused of killing Pagerly in Albany Township on June 29.

Connor and Engleman are accused of supplying guns to Matthew Connor, including the one he used to kill Pagerly as a team of law enforcement officers attempted to arrest him. Connor was also killed in the exchange of gunfire.

An investigation by the Berks County district attorney's office revealed that Keim, the mother of a friend of Matthew Connor's, bought him three handguns, two in 2004 and one in 2005, according to court documents. None was used in the killing of Pagerly, police said.

Matthew Connor was not legally allowed to own or possess any firearms because of numerous run-ins he had with the law since 2000, police said.
