WILLIAMSPORT -- A Philadelphia native who had been released from prison three months ago has been charged with the murder of a mother and her adult son in their Williamsport residence on Halloween night.

Jordan A. Rawls

Jordan Adonis Rawls, 24, turned himself in to city police Friday evening after learning he was a person of interest in the double homicide.

Agent Trent Peacock said Rawls was unaware there was an arrest warrant charging him with two counts each of criminal homicide and conspiracy to commit robbery along with one count each of robbery, attempted robbery, convicted felon not to possess a firearm, possession of a firearm without a license and possessing an instrument of crime.

Rawls, who was committed to the Lycoming County Prison without bail, told District Judge Christian D. Frey he is on probation after completing a two-year sentence for armed robbery in Philadelphia under the name Richard Rawls.

Rawls, who is unemployed, has a girlfriend and address in Williamsport but returned to Philadelphia for a time after the shooting, Peacock said.

Joseph Sentore Coleman Jr.

Still sought for the murders of Kristine Kibler, 50, and her son, Shane Wright, 25, is Joseph Sentore Coleman Jr., 25, who has a record of drug arrests in Lycoming County.

The arrest affidavit alleges Rawls and Coleman planned to rob Wright in the half of double house in the 600 block of Poplar Street in which he, his mother and others lived.

A third man, who is cooperating with the police, told them he had been coerced by Coleman, who previously had threatened to kill him and his family for testifying against him in a 2013 robbery case.

The man told police that on the evening of Oct. 31 at Coleman's request he picked him up and then Rawls.

He said he heard them plan to rob Wright and that Coleman knew he sold marijuana and Molly, a synthetic psychoactive drug, the affidavit alleges.

That individual, who has not been charged, told investigators he was directed by Coleman to go into the Poplar Street house to determine the location of Wright and other occupants.

When he returned to the car, Coleman and Rawls, each with a handgun, went into the house just before 10 p.m., after which he heard two gunshots, he told police.

The unidentified man then drove Coleman and Rawls from the scene, the affidavit states.

Wright was discovered dead from a head wound at the front door, police said.

Kibler, who was shot in the abdomen, died a short time later at Williamsport Regional Medical Center.

Wright's sister, Cheyanna Wright, told police she and her boyfriend heard a scuffle outside their bedroom and saw a masked gunman holding onto Kibler.

Cheyanna Wright told investigators she and her boyfriend retreated into their bedroom when the gun was pointed at them. After they heard a gunshot they found Kibler in the hallway, she said.
