MISSING BAYLOR PLAYER Investigators' search for body of Dennehy comes up empty

His former roommate has been charged with murder.
WACO, Texas (AP) -- Despite a day of fruitless searching for missing Baylor basketball player Patrick Dennehy, police expect to find his body based on information from his former teammate, who is charged with his murder.
Investigators, some on horseback, searched river banks and a gravel pit Tuesday for Dennehy's body.
Police Sgt. Ryan Holt said authorities would keep searching, but wouldn't say where.
"There is always the hope, very sincere hope, that we find Mr. Dennehy, mostly for his family and then for the criminal case," Holt said.
Former roommate Carlton Dotson, 21, was charged Monday night with murder after he confessed to FBI agents that he shot Dennehy in the head "because Patrick had tried to shoot him," according to an arrest warrant released Tuesday.
"Mr. Dotson provided specific information about the murder of Mr. Dennehy that would lead us to believe he committed the murder," Holt said, declining to release more details.
Denies confession
As he left the Kent County courthouse Monday, Dotson told a reporter: "I didn't confess to anything."
Dennehy, 21, was last seen on campus on June 12; his family reported him missing on June 19. The next day, Waco police said Delaware police told them an informant said Dotson told someone he shot Dennehy in the head after the two argued.
Dotson was seen "during the late evening" on June 12 in Sulphur Springs, the hometown of his estranged wife, driving Dennehy's Chevrolet Tahoe, and told someone he planned to go to Maryland, the warrant said.
Dennehy's Tahoe was found abandoned, without license plates, in a Virginia Beach, Va., mall parking lot June 25.
On Sunday, Dotson contacted authorities near his hometown in Maryland, said he was hearing voices and later, after being taken to a hospital, asked to speak with FBI agents about Dennehy's disappearance, authorities said.
Dotson attorney Grady Irvin said Tuesday that he hadn't spoken to his client since his arrest.
"I don't think he's in a mental state right now to be speaking to anyone in any lucid fashion," Irvin said.
"A guy goes in for a psychological evaluation and it turns into a police interrogation," he said. "How that happens, I don't know."
Irvin said he would examine the arrest warrant and see if any comments that Dotson made in recent weeks were included.
"If it is, there is a significant likelihood that his competency to make those statements are in question," he said.
Held without bond
Dotson was ordered held without bond in Maryland on Tuesday. An extradition hearing was set for within 30 days after the defense refused to waive the right to such a hearing and allow Dotson's immediate transfer to Texas.
Dotson and Dennehy were on the basketball team at the Baptist university last season. Dotson recently lost his scholarship and was not planning to return to Baylor in the fall.
Dotson's estranged wife, Melissa Kethley, said she's known that Dotson needed psychological help for a long time.
"He needs help, the boy needs help," a tearful Kethley said in a telephone interview.
"Maybe, if he did do this, it's a blessing in disguise, and he can get the help he needs," she said.
