CHESTERTOWN, Md. -- A day before he was charged with killing his roommate, Carlton Dotson called 911, calmly said he had an emergency, and asked dispatchers to let police from his home county know where he was.

Dotson, using a cell phone, called 911 twice Sunday from a Super Fresh grocery store in Chestertown.

The calls lasted a total of about two minutes, said Kent County Attorney Susanne Hayman, who deleted about 20 seconds of the material before releasing it Wednesday. The deletions were made because at three points, Dotson or the dispatchers discussed his medical or psychological condition, she said. That information is protected under state law, Hayman said.

After the calls, two Chestertown police officers and a Kent County sheriff's deputy took Dotson to Chester River Hospital Center in Chestertown, where he spent the night.

Dotson, 21, was arrested the next day after an interview with FBI agents, during which authorities said he confessed to shooting his former Baylor University basketball teammate, Patrick Dennehy.

Dotson is being held in the Kent County Detention Center as his lawyers contest his extradition to Waco, Texas, where authorities believe the killing occurred.

When a dispatcher asked Dotson if he had an emergency, he answered: "Yes, ma'am ...'' Hayman deleted the rest of his answer from the recording.

A few seconds later, he identified himself as Carlton Dotson, adding: "I'm the ...'' but didn't finish the sentence.

Next, he said, "I would like for you to also let the Dorchester County police know.'' Hayman deleted the next section of the tape, but the dispatcher is then heard asking Dotson if he was wanted by deputies in the nearby county of Dorchester. "No, I'm not wanted by them, but they wanted to keep close tabs on me,'' he replied.

Dorchester County Sheriff James Phillips Jr. said Wednesday his department was not surveying Dotson and didn't restrict his travel. He said he was not aware Dotson had asked for his deputies to be contacted.

Dotson also told the 911 operator that he was wearing blue jeans and a white T-shirt, and he gave her his cell phone number.

About five minutes later, Dotson called 911 to find out if authorities were on their way and another dispatcher told him they were.

Three days earlier, Dotson had contacted the Dorchester sheriff's office, near his hometown of Hurlock, and asked to speak with deputies. He gave a statement to a detective and an FBI agent, then left with no charges being filed.

"There was nothing there. There was no reason to hold him or tie him to anything,'' Phillips said Wednesday. "We had no reason to tell him to tell us where he was going. As far as we were concerned, he could go where he wanted to.''
