WACO, Texas -- A former teammate and roommate of Baylor basketball player Patrick Dennehy provided few leads in Dennehy's disappearance when he gave a statement to authorities, the missing athlete's family said.

Dennehy's stepfather said Waco police briefed the family about Carlton Dotson's rambling two-hour statement to authorities near his Maryland hometown.

"From my understanding, (Dotson) didn't really say anything that had any bearing on Patrick's case ... any actual information or anything they needed," Brian Brabazon told The Dallas Morning News. "I'm kind of exasperated, just because it looks like there's a lot happening, and then nothing happening at the same time.

"It came across that Carlton may have just been yanking someone's chain," Brabazon said to the Morning News. "The impression I got was that maybe some of Carlton's family members are wondering why he's not saying something, and that's what pushed him to go to police."

Waco police Sgt. Ryan Holt would not discuss what Dotson told authorities, except to say "It is not going to change the course of the investigation at this time."

Dotson voluntarily went to the sheriff's office in Dorchester County, Md., on Thursday to give his statement. A source close to the investigation told ESPN.com that Dotson went into the interview session holding a bible and quoted the scripture numerous times throughout the questioning. He was never in custody.

Dotson's attorney, Grady Irvin Jr., did not immediately respond to a call seeking comment Saturday.

Authorities said Friday they were trying to determine if a 9mm handgun found Thursday at a Waco apartment complex near Baylor is related to Dennehy's disappearance.

According to a search warrant affidavit, an unidentified informant told Delaware authorities that Dotson told a cousin he shot Dennehy as the two argued while shooting 9mm guns in the Waco area.

Friends have said Dennehy and Dotson told them they bought guns because they had been threatened.

Dennehy's girlfriend told police that he had been threatened by a man named Harvey, according to the affidavit.

Harvey Thomas, who transferred from Fredericksburg, Va., to play basketball for Baylor this season, lives at the apartment complex where the gun was found, some neighbors said.

Thomas' stepmother, Tempia Thomas, has said that police questioned him. Other players also have been questioned.

Police have said Dotson is not the only "person of interest" in the case, but have not named Thomas. "Any person that was close to Mr. Dennehy in any capacity is a person of interest," Holt said.
