Riverside, California (CNN) -- Authorities said Wednesday they are reasonably sure that the body found inside the burned cabin near Big Bear Lake, California, is that of Christopher Dorner, the rogue ex-cop who had been pursuing a vendetta against his fellow officers.

"We believe that this investigation is over, at this point, and we'll just need to move on from here," San Bernardino Sheriff John McMahon told reporters.

Although the description and behavior of the man who was killed are consistent with Dorner, officials "cannot absolutely, positively confirm it was him," McMahon said.

"We're not currently involved in a manhunt," he said. "Our coroner's division is trying to confirm the identity through forensics."

Authorities say Dorner launched a guerrilla war against the Los Angeles Police Department over what he considered his unfair dismissal in 2009.

McMahon identified a sheriff's detective who was fatally shot Tuesday by the man presumed to have been Dorner as Jeremiah MacKay. MacKay, 35, was a 15-year veteran who was married with two children, a 7-year-old daughter and a 4-month-old son.

Another officer has undergone "a couple of different surgeries" after being wounded in the shootout. "He's in good spirits and should make a full recovery after a number of additional surgeries," McMahon said.

The two men were ambushed Tuesday when they responded to a report of a vehicle stolen by a suspect matching Dorner's description, McMahon said.

"It was like a war zone, and our deputies continued to go into that area and tried to neutralize and stop the threat," McMahon said. "The rounds kept coming, but our deputies didn't give up."

The suspect then fled into a nearby vacant cabin, which caught fire after police shot tear gas canisters into it, McMahon said.

Although the canisters included pyrotechnic tear gas, which generates heat, "We did not intentionally burn down that cabin to get Mr. Dorner out," McMahon said.

It wasn't clear when a formal identification could be made of the charred remains found in the cabin about 100 miles east of Los Angeles after Tuesday's shootout with police. Until then, "a lot of apprehension" remains in the ranks of the LAPD, Lt. Andy Neiman said.

'A very trying time' for the LAPD

"It's been a very trying time over the last couple of weeks for all of those involved and all those families, friends and everybody that has been touched by this incident," he said.

On Wednesday, police from around the Los Angeles area and beyond gathered to bury Michael Crain, who was among the four people fatally shot, allegedly by the 33-year-old former Navy officer.

Dorner also killed the daughter of a former LAPD captain and her fiance and shot three other officers, including Crain's partner, police say.
