MAPLEWOOD, Minn. - Police have identified a Maplewood hospital patient who allegedly attacked nurses on Sunday, then died after police handcuffed him.

Authorities say Charles Emmett Logan, 68, of St. Paul was pronounced dead at St. John's Hospital. They are still investigating how he died.

According to police, Logan, who had been hospitalized with episodes of confusion, assaulted four nurses with a metal pole around 2 a.m. at St. John's Hospital, and then fled the building.

"This was a violent attack and was quite unexpected," Maplewood police chief Paul Schnell said.

The nurses who were assaulted include a 40-year-old from Wyoming, Minnesota, a 22-year-old from Brooklyn Park, a 32-year-old from Lino Lakes, and a 30-year-old from Hudson, Wisconsin.

One nurse sustained a collapsed lung, another had a fractured wrists and two more nurses suffered cuts and bruises.

After Logan took off, police found him three blocks away and ordered him to drop the bar, but he refused.

Police attempted to use a taser device on him, but it wasn't effective. That's when two Ramsey County sheriff deputies and a Maplewood police officer took him to the ground and handcuffed him.

Moments later, Logan was unresponsive. He was taken to St. John's Hospital where he was later pronounced dead. Schnell does not know what caused the violent episode, but did say medical staff noted paranoia before the attack. He says their preliminary investigation indicates other hospital patients were never the focus of the attack.

"It is fortunate that hospital personnel were not more seriously injured in the unprovoked attack," said Schnell. "While what prompted the attack may never be known, we await completion of the Ramsey County Medical Examiner's inquiry, which we hope might answer questions about Mr. Logan's status for the sake of his family and all those involved in this incident,"

The Minnesota Bureau of Criminal of Apprehension is investigating. The deputies and officer were put on standard leave in accordance with policy.
