OCALA, Fla. -- Autopsy results are expected Monday in the gruesome murder of two campers deep in the Ocala National Forest. The bodies of Amber Peck and John Parker were found shot to death early Saturday morning.

Monday, investigators returned to the scene of the crime for a third day, but getting there is anything but easy.

"In my 34 years with the sheriff's office, probably one of the most inaccessible crime scenes I’ve ever seen," said Capt. Dennis Strow, Marion County Sheriff's Office.

Deputies said the murder scene is more than two miles off the nearest dirt road, in an area restricted to motorized vehicles and cut off by water that, at times, is waist deep. It’s a crime scene so remote that the medical examiner used a helicopter to fly the bodies out and evidence so difficult to gather, the investigation took seemingly forever to get underway.

"That's what makes this case difficult, because until you start narrowing some of this stuff down, it's kinda hard to come up with a motive," Strow said.

The only thing detectives could say for sure was that 26 year olds Amber Peck and John Parker were the victims of a cold-blooded murder.

The pair had left their homes near Gainesville on Tuesday on an overnight camping trip. But, by Friday, when they hadn't returned, roommates filed a missing persons report.

By the weekend, with the search focusing on the Juniper Prairie Wilderness Area in the Ocala National Forest, it was family members who made the devastating discovery at their campsite.

Now investigators have begun the race for answers knowing by now whoever killed them could be anywhere.

"Do you have someone who maybe perpetrated this crime who was a total stranger, who encountered them on the trail or was it an acquaintance from the Alachua County area?" Strow questioned.

Peck and Parker were students at Santa Fe Community College in Gainesville. Information and counseling sessions are scheduled Monday on the college's campus.

Authorities are urging anyone with information about the slayings to call the Marion County Sheriff's Office. The reward for information in this case now stands at $5,000.
