UPDATE: Wednesday, 2:00 p.m.

The guard severely beaten in an assault near the Carson City Correctional Facility Tuesday is still in critical condition, but recovering in a Lansing Hospital. The guard, Sam Olivo, has been with the Michigan Department of Corrections for more than 22 years.

"Our Director, Deputy Director and the facility warden all went up to see him in the hospital today," Russ Marlin of the Michigan Department of Corrections told FOX 17. "He is still intensive care but showing some positive signs. We are hopeful and have Officer Olivo and his family in our thoughts and prayers."

F/Lt. Curt Schram of the Michigan State Police tells FOX 17 that the investigation indicates that only one inmate, 39 year old Daniel Henry, attacked Officer Olivo and stole the van, while the other four inmates remained locked in back of the van. The other inmates were forced to stay in the van as Henry tried to escape, driving the van to Dimondale before ditching it, with the inmates still locked in the back.

F/Lt. Curt Schram says the Eaton County prosecutor will likely file charges against Henry for a traffic-related incident in the coming days, then felony charges for escape and attempted homicide will be requested by Michigan State Police in Montcalm County for the attack on the guard. If convicted on those charges, the sentence will be added to Henry's current sentence for breaking and entering, which expires in 2034. _________________________

The search is over for five escaped prison inmates near Lansing. They are all back in custody.

"It certainly doesn't happen very often so I think it's a shock and fortunately they were arrested before any serious injuries to the public. We got them in custody where they belong,"said Lt. Curt Schram with Michigan State Police.

The five inmates from the Carson City Correctional Facility were on a work detail Tuesday at 11:45 a.m., about a mile north of the prison, when one assaulted a guard and stole his van.

"They were being guarded by one Department of Corrections guard who was not armed. Of the 5 inmates we're not sure how many of them overpowered the guard and caused serious injuries to him. They did strike him with an unknown object we're still investigating it," said Schram.

Michigan State Police say the guard, who was seriously injured, was able to walk to a house about 100 yards away and the homeowners called 911. That's when law enforcement were alerted of the situation.

"I had no idea what was going on. The neighbor had called and said there's a man that is disoriented," describes neighbor Nancy Ngele.

She lives about a 100 yards from where it all happened.

Her neighbors, The Palmers, helped the guard and called 911.

"Well it was really scary to think about prisoners running around," she said.

The guard is currently at Sparrow Hospital in Lansing being treated for his injuries. The Michigan Department of Corrections deployed it's Emergency Response Team, and contacted State and local police departments with an All-Points Bulletin.

Police say the men drove southwest of Lansing, to Dimondale, where an alert Michigan State Trooper saw the van and tried to stop it. Michigan Department of Corrections spokesman Russ Marlin says the driver, Daniel Henry, ditched the van and took off running. Four of the inmates were caught immediately still locked in the van, but Henry was able to hide from police for nearly an hour before being caught.

Marlin identified the inmates as: Dennis Hall, 45 Andrew Lang, 50 Ranar Cook, 28 Lucas Schuster, 28 Daniel Henry, 39

All five were taken in for questioning and are now back in custody at the correctional facility.

"I soon heard four had been caught then the 5th, so that's a relief but we're still caught up in the trauma of the whole situation," said Ngele.

The MDOC officer who was attacked is in critical condition at Sparrow Hospital. 55-year old Sam Olivo has swelling on his brain. He had emergency surgery and doctors say the next 72 hours are crucial.

Friends and family are praying he will pull through.
