Hundreds of pages of documents contain new information about how two Winter Park High School students were killed.

Those documents, released Tuesday, shed new light on what led to the murders of Nicholas Presha and Jeremy Stewart.

After interviewing several witnesses, investigators were able to put together a timeline of the teens' brutal last hours.

What follows is a summary of the events of that night, according to those documents.

Just after midnight on April 15, Presha sneaked out of his parents’ home to meet Stewart.

The two went to the RaceTrac gas station on Aloma Avenue and asked one of the suspects, 31-year-old Hector Rodriguez, to buy them beer.

Rodriguez bought the beer around 1 a.m., investigators said.

Then, just after 2 a.m., the teens were spotted with Rodriguez and the other suspect, Jesse Davis, at a Steak 'n Shake restaurant.

While there, Rodriguez told investigators both boys said they had stolen guns for sale.

Presha had his gun on him.

Davis drove Stewart home so the teen could get the stolen .40-caliber Glock handgun he wanted to sell.

The four eventually ended up at Davis' mother's home.

That's where witnesses inside the home said the men took the guns from the teens, hit them, ordered them to undress and get on the ground, and then the suspects tied the teens' hands.

From there, investigators said the teens were loaded into a car that belonged to Davis' mother.

Around 5:48 a.m., surveillance video from the Citgo gas station on Metric Drive showed Davis buying $5 worth of gasoline and looking into the trunk of the car, investigators said.

Within 20 minutes, three bicyclists found Presha and Stewart's burned bodies just off the Cady Way Trail.

Investigators said Rodriguez told people the boys were shot "execution style."

According to autopsy reports, Stewart died after a single shot to the back of his head.

Presha was shot three times -- once in the back of the head, and then twice in the face before he died.

Their bodies were doused with gasoline and set on fire.

Both Davis and Rodriguez are being held without bond.

Davis' attorneys filed a motion for a competency hearing after they said their client was evaluated by psychiatrists who said he is not competent to stand trial.
