WACO, Texas - Investigators on foot and horseback searched a gravel pit near the Brazos River on Tuesday for the body of Baylor basketball player Patrick Dennehy, who police believe was killed by a former teammate.

The teammate, Carlton Dotson, was charged with murder Monday in Chestertown, Md., near his hometown. He was ordered held without bail Tuesday, and his attorneys said they would oppose his transfer to Texas.

The search was centered just miles from the Baptist university where Dotson and Dennehy were on the basketball team last season. The search began after Dotson spent two hours Monday with authorities in Maryland, where he lives.

Dotson, 21, admitted to FBI agents that he shot Dennehy in the head "because Patrick had tried to shoot him," according to an arrest warrant released Tuesday.

Outside the Chestertown courthouse Monday, Dotson told a reporter: "I didn't confess to anything."

Defense attorney Grady Irvin said he had not spoken to Dotson since his arrest. He said he would examine the arrest warrant to see if any comments 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," Irvin said Tuesday.

Dennehy, 21, was last seen on campus June 12, and his family reported him missing June 19. The next day, Waco police said an informant reported that Dotson told someone he shot Dennehy in the head after the two argued.

Dotson was seen on June 12 in the Texas hometown of his estranged wife, driving Dennehy's Chevrolet Tahoe. The vehicle was found abandoned, without license plates, in Virginia on June 25.

Dotson went to Chestertown, about 55 miles from his hometown of Hurlock, Md., on Sunday and called 911, Chestertown Police Chief Walter T. Coryell said. When officers arrived, Dotson told them he "needed counseling" and was hearing voices. The officers took him to a hospital for evaluation, where Dotson asked to speak with FBI agents, authorities said.
