CHESTERTOWN, Md -- The roommate of missing Baylor basketball player Patrick Dennehy was ordered held without bail on a murder charge Tuesday and his lawyers opposed his extradition to Texas.

Carlton Dotson Jr. was arrested Monday on a warrant obtained by police in Waco, Texas, where both men attended Baylor, said Police Chief Walter T. Coryell.

Kent County Deputy State's Attorney Joseph Flanagan said Dotson "made strong self-incriminating statements'' when he talked to FBI agents on Monday. Dotson told a reporter outside the courthouse Monday: "I didn't confess to anything.''

But a source close to the investigation told ESPN.com's Andy Katz on Tuesday that authorities are acting on information from Dotson in narrowing their search for Dennehy's body and are concentrating on a lake near Waco.

His estranged wife said Tuesday he needs psychological help, but that she does not believe he killed Dennehy.

Flanagan told the judge at Tuesday's bail hearing that the charge Dotson faced -- "murder with intended death'' -- was a capital offense in Texas.

Dotson, 21, was questioned for at least two hours Monday by three FBI agents, Coryell said. A Waco police detective also was present.

Shortly after the questioning, Waco police obtained the warrant.

An extradition hearing was set for within 30 days after the defense refused to waive the right to such a hearing and allow the Maryland man's immediate transfer to Texas.

Outside the courtroom, defense attorney Sherwood R. Wescott said the decision not to waive extradition was a "strategic move.'' He would not comment Tuesday on whether Dotson had confessed to killing Dennehy.

Waco police Sgt. Ryan Holt told The Dallas Morning News that Dotson confessed to killing Dennehy and described a location where Dennehy's body might be found. He told the newspaper that police searched there Monday night, but would not elaborate. He said the department would not comment further until a news conference scheduled for Tuesday afternoon.

"Carlton, if you know where our son is, please let us know,'' Dennehy's mother, Valorie Brabazon, said Tuesday on ABC's "Good Morning America.'' She said she still feels "that my son is out there somewhere alive.''

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

Dotson's relatives have told authorities that Dennehy's body is "buried in a large body of water,'' the Tribune-Herald reported, citing a source close to the investigation.

Dotson came to Chestertown, about 55 miles from his hometown of Hurlock, on Sunday and Coryell said he used his cell phone to call 911. Police said they weren't sure why he came to Chestertown. Wescott's law partner, Purcell Luke, said in court Tuesday that Dotson's mother has lived in the Chestertown area for three years.

When officers arrived, Dotson told them he "needed counseling'' and was hearing voices, Coryell said.

The officers took him to a hospital, where he was evaluated but not admitted. While still at the hospital Monday afternoon, Dotson asked to speak with FBI agents, authorities said.

Calls to the FBI were not returned.

Dotson's estranged wife, Melissa Kethley of Sulphur Springs, Texas, said she cannot believe Dotson killed Dennehy. She wouldn't elaborate or discuss their marriage.

She said that although Dotson called and told her Monday that he was talking with the FBI, he didn't tell her he had been to the hospital.

"But I've known that he's needed psychological help for a very long time,'' Kethley said, crying, during a telephone interview. "He needs help, the boy needs help. ... Maybe, if he did do this, it's a blessing in disguise, and he can get the help he needs.''

Dennehy's vehicle was found June 25 in Virginia Beach, Va.

Friends say Dennehy told them that he and Dotson obtained guns because they were being threatened. Dennehy's family also claimed the 6-foot-10, 230-pound forward told coaches he feared for his life.

Dennehy's girlfriend, Jessica De La Rosa, held back tears Monday night after she learned Dotson was charged with killing him.

"I was really, truly hoping in my heart that he was alive somewhere out there,'' said De La Rosa, 20, of Albuquerque, N.M. "I was hoping maybe he'd be hiding.''

Baylor Athletic Director Tom Stanton issued a statement saying, "We are struggling to find the right words and actions that would ease the pain of everyone connected to Patrick. ... There are no words to describe our grief or our feelings right now.''

Dennehy's vehicle was found June 25 in a strip mall parking lot in Virginia Beach, Va., where he had no apparent connections.

Friends of Dennehy's say he told them that he and Dotson were being threatened and that the pair obtained guns. The family of Dennehy, who grew up in the San Francisco area, also claimed the 6-foot-10, 230-pound forward told coaches he feared for his life.

Dotson lost his basketball scholarship this spring and was not expected to play at Baylor next season.
