A judge is expected to rule today on whether or not the arrest warrant issued by the State College Police Department to detain former Penn State football player Lavon Chisley in a Maryland jail was legally obtained.

Chisley has been identified as a person of interest in the murder of Penn State senior Langston Carraway. Carraway was found stabbed to death in his Northbrook Lane apartment June 5.

At his hearing yesterday morning in front of Centre County Judge Charles Brown, Chisley's lawyer, Karen Muir, argued that the law requires a summons be filed -- which would require Chisley to turn himself in -- unless there is reason for the district judge to believe he would not obey the summons.

In this case, Centre County District Attorney Michael Madeira said the exception was met because Chisley's whereabouts were unknown.

Police placed a detainer on Chisley after they searched his ex-girlfriend's State College apartment and found marijuana that she claimed he left behind. The detainer will keep Chisley in prison in Ann Arundel, Md., where he is currently facing similar drug charges, regardless of whether or not he makes bail.

But because Chisley has not made bail in Maryland, Madeira said it "disingenuous" to claim the detainer is what is keeping him locked up.

Patton Township Police officer Eric Haas testified at yesterday's hearing that Chisley was living with the brothers of Carraway until the day before he was found dead in his apartment.

Muir said from what she has been told, Chisley was friends with Carraway, but left State College for Atlanta on June 4 to attend training camp for the NFL.

Although Madeira identified Chisley as a person of interest in Carraway's death, he said he has no plans to press charges against him for homicide.

Still, Muir insists that she has sources that tell her Chisley will be charged with the homicide. Chisley denies any connection with Carraway's murder , Muir said.

"[Muir] said 'Aw, c'mon, you know you're going to arrest him,' " Madeira said regarding a phone conversation he had with Muir yesterday. "She has a source who says he's going to be arrested, but I get to make that decision, and I have not made that decision. The source is clearly inaccurate."

Muir said she is not at liberty to discuss whether or not Chisley plans to cooperate with police questioning.

However, Madeira said that Muir told police officers that Chisley would not cooperate with the investigation.

Madeira said July 19 that he wants to ask Chisley questions about his relationship to Carraway, just as he did when questioning other friends and family.

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.

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