The possibility that former Penn State football player LaVon Chisley once lived with Langston Carraway's parents partially led investigators to name Chisley as a person of interest in the case of the Penn State senior who was stabbed to death in June, Centre County District Attorney Michael Madeira said.

Madeira said part of the DNA evidence recovered from the scene of the June 5 stabbing of Carraway at his apartment, 110 Northbrook Ln., apt. 201, was returned, but he would not comment on what evidence he received or whether it contains any new information. He also would not say what evidence police are still waiting for.

Madeira said certain things found at the crime scene have led investigators to believe drugs and robbery could have been a motive for the murder.

"The direction we are going is drugs," Madeira said. "But it's not rock solid. That is a stretch."

Although Madeira said police have named Chisley a person of interest, he said there are no plans to charge him and police simply want to question him like they have questioned family, friends and neighbors of Carraway.

"We want to talk to him to see if he knows anything about the homicide," Madeira said. "This is just another friend of Carraway's."

Repeated attempts to contact Karen Muir, Chisley's attorney, were unsuccessful yesterday.

Madeira said the District Attorney's office has made no contact with Muir regarding any aspect of the homicide investigation.

"We haven't said 'hey, we are interested in talking to your guy,' " he said. "No one from our office has said anything to her."

Madeira said Chisley came under the radar after police realized he left Pennsylvania after Carraway's death and did not contact the family or attend the funeral.

"To us, it seems odd," Madeira said. "If he is as close as everybody thought he was [to Carraway], why wouldn't he be there? But, at this point he is just somebody we want to talk to."

Chisley is currently being held in Maryland on charges for possession of marijuana, according to the records office at the detention center in Ann Arundel, Md.

Because Chisley is also facing drug-related charges in Centre County, a detainer has been placed on him -- which prevents his release from the Ann Arundel detention facility, where he is being held in lieu of $2,700 bail since being arrested July 14.

Madeira said the detainer is in no way related to the homicide investigation.

A preliminary hearing for Chisley's charges in Ann Arundel has not yet been scheduled, but once Chisley clears up his legal problems in Maryland, Madeira said he would be extradited to Centre County to face the drug charges.

"It is our intention to bring him back," Madeira said.

Carraway's death was ruled a homicide on June 6, one day after he was found in his apartment by a family member who reported that he did not have a pulse, according to a Patton Township press release.

Centre County Coroner Scott Sayers said Carraway died of "massive blood loss as a result of a stabbing." He would not say how many times Carraway had been stabbed or where the wounds were located.

Madeira said police still do not have any suspects in the murder.

Carraway's family declined to comment.
