The man accused of stabbing a Penn State senior to death in June told police three weeks after the murder that his friend, the victim, dealt marijuana by the pounds, police said.

LaVon Chisley -- who is charged with the first- and third-degree murder of Langston Carraway -- said Carraway was an active marijuana dealer during a June 24 phone conversation with Patton Township police officer Tom Snyder, court documents indicate.

Chisley also told Snyder that on June 3, two days before Carraway's body was found, he was at Carraway's residence, 110 Northbrook Lane, when he witnessed a white woman purchase marijuana from Carraway, Centre County District Attorney Michael Madeira said.

Carraway, 26, was stabbed and slashed 93 times with multiple knives on his neck and the right side of his torso and face; his multiple injuries also include what a doctor determined were defense wounds on both arms, according to court documents.

Court documents state that the murder took place between 8 p.m. June 3 and 6:30 a.m. June 4. A family member found Carraway's body the afternoon of June 5 on a couch in his apartment, police said.

Chisley, 23, was arrested Tuesday for his alleged role in Carraway's murder after he voluntarily turned himself in to police at the Centre County Courthouse in Bellefonte.

In October, Chisley's attorney, Karen Muir, stated in court documents that Carraway was a "known dealer" of drugs in Centre County.

Madeira would not comment on whether drugs were present at Carraway's apartment when it was searched after the murder or if he and other authorities believe drugs were taken in commission of the murder.

"It doesn't matter whether it was true if Carraway was a drug dealer or not," he said.

However, Madeira said he thinks drugs were "part of the equation" in the murder.

"But I would not say that it was drug-related in the sense of, you know, because someone was high on drugs, or a direct connection," Madeira said, adding that there is no indication that the accused, Chisley, was impaired by drugs when authorities allege he killed Carraway.

Muir said Tuesday that "to the best of [her] knowledge" Chisley is not involved in drugs.

Robbery is being investigated as Chisley's motive for Carraway's slaying, Madeira said.

"And if Chisley believed [Carraway] was [a drug dealer], and Chisley thought he had money, then our theory on the motive is, then Chisley would have realized he could get money from Carraway," Madeira said.

Since late June, Chisley was called a "person of interest" in Carraway's murder.

In October, Chisley faced drug-related misdemeanor charges in Centre County for alleged possession of a scale and a small amount of marijuana, which was found in his ex-girlfriend's apartment, police said. The ex-girlfriend told police the scale belonged to Chisley, according to court documents.

Chisley was cleared of the drug charges because he was no longer living at the residence where the paraphernalia was found, and the criminal complaint against him was not amended with the specific dates police alleged he was in possession of it within a certain time period.

In a motion Muir filed in October, she argued for the charges to be dismissed because Chisley was not the owner of the scale or marijuana; instead, she said in the motion that Chisley claims Carraway was the owner.

According to court documents, Penn State University Police charged Carraway with possession of a small amount of marijuana for personal use on March 27.

Carraway was found neither guilty nor innocent of this charge because of his June death.

According to the controlled substances, drug, device and cosmetic act, a small amount of marijuana is defined as an amount of up to 30 grams. The offense Carraway was charged with is punishable by a maximum sentence of 30 days in prison, a fine up to $500, or both.

Carraway's family could not be reached for comment. Carraway's father, Vernon, is a counselor in educational equity at Penn State.
