“He seemed off somehow, didn’t he?” Denner asked.

“Yes,” Boyle confirmed.

Yesterday afternoon, Lynch called to the witness stand the four emergency medical technicians who took Pring-Wilson from the police station to Cambridge Hospital when he started to complain of head pain the afternoon after his arrest.

Robert Kallen and Alexei M. Wagner testified that they took Pring-Wilson to Cambridge Hospital on April 12, 2003, when he first complained of head pain, and Kathleen Ahern and Joseph Johnson said they took him the next day, when he allegedly said his condition had worsened.

All four EMTs said that Pring-Wilson was behaving normally and cooperated with them on both days.

When Denner asked about the brief examinations they conducted in the police station before taking Pring-Wilson to the hospital on both days, none of the EMTs said they saw external signs of injury.

But Ma, the physician, testified that Pring-Wilson had several superficial lacerations.

The rest of the motion’s witnesses, including psychiatric and medical experts, are scheduled to testify today, and the hearing will continue next week if necessary.

On Feb. 24, Denner filed a motion to move the trial to western Massachusetts, claiming that a Cambridge jury is likely to be biased because of the case’s extensive media coverage.

Judge Grabau said yesterday he will hear arguments on this motion after he rules on the current motion to suppress evidence.
