After an exhaustive investigation, authorities arrested two teens suspected of killing Bodhisattva "Bodhi" Sherzer-Potter, 16, and Christopher Cody Thompson, 18, on Jan. 5 following a party in an abandoned military bunker.

Collin Lee McGlaughlin, 18, of West Covina and David Brian Smith, 19, of Covina were arrested Thursday night on suspicion of murder, Cindy Beavers, spokeswoman for the San Bernardino County Sheriff's Department, said Friday.

Sherzer-Potter of Helendale and Thompson of Apple Valley were found dead in the bunker the day after a large party took place there.

When the teens did not return home, concerned parents contacted a friend who returned to the bunker to look for them and found them dead, officials said.

Authorities say those arrested knew someone in the High Desert and that is how they heard about the bunker. Although they were at the same party as the victims on Jan. 4, it seems they were not directly invited.

"They initially believe the motive was robbery. However the investigation doesn't show any property taken from victims," Beavers said. "I think that was their motive, and then it turned deadly."

Sherzer-Potter and Thompson were both shot, execution style, and authorities say there were no signs of struggle.

During the investigation search warrants were served in Los Angeles County and in Mira Loma in Riverside County as homicide investigators worked the case. Weapons were recovered in those searches and the guns will be tested to determine whether they were those used in the murders.

Officials also suggested that the fathers of both alleged killers were involved in law enforcement.

Bodhi's name was graffitied in the bunker where the teens were found, but Beavers said it was unclear whether that was related to the crime.

"We don't know if it's related or if it was done afterward. We don't know if it had anything to do with the crime."

Despite widespread speculation that Sherzer-Potter was also the victim of rape, sheriff's officials said it remains unclear whether that was the case.

"As far as the sexual assault goes, that is something that I'm sure they tested for during the autopsy but they haven't released anything because there are no results yet," Beavers said.

After working the case non-stop for several days, authorities were out of leads and asked for the media's assistance in asking witnesses to come forward. The Daily Press, sister paper to the Desert Dispatch, ran a brief with contact information nearly every day since the information was put out.

Eventually, a tipster contacted the Sheriff's Department with information that led to McGlaughlin and Smith.

Sheriff's officials praised the media.

"I have to say that the credit goes to the Daily Press and to NBC for the coverage on this," Beavers said. "(Detectives) were trying to work a double murder with no leads and it was extremely frustrating for them, but the media kept people talking about it."

After their arrests at their homes Thursday, McGlaughlin was booked into West Valley Detention Center and Smith was booked into Central Detention Center, Beavers said.

Deputy District Attorney Steven Sinfield said he anticipates filing charges of murder and attempted robbery on both men.

McGlaughlin is alleged as the shooter. Sinfield said he anticipates filing a special allegation of personally or deliberately discharging a firearm causing death.

"Smith also used a gun but didn't discharge it," Sinfield said.

If convicted of the charges, McGlaughlin faces at least 100 years to life in prison and Smith faces at least 70 years to life in prison.

Their arraignment is expected to be held Tuesday in the Barstow Superior Courthouse.

In the words of an alleged killer By KATHERINE ROSENBERG

He called himself an "Equal opportunity merchant of death."

Collin Lee McGlaughlin, 18, who is suspected of murdering two teens execution style, left behind a chilling Myspace page that repeatedly talks about the kind of violence carried out on Jan. 5.

"I entered this world screaming and covered in someone else's blood and that's how I intend to leave it," McGlaughlin wrote.

In a blog entry on his page titled, "if u dont read this i will sneak into your house late at night and kill u," McGlaughlin outlined his perspective on the world.

On a numbered list he included, "u may be able to outrun me but can u outrun a bullet???" followed up with, "i feel that if a person really needs it they should be able to walk down the street with a .357 killing people at random."

Then there are the guns.

McGlaughlin is seen holding a pistol-grip shotgun in one photo and a handgun in the other with the caption, "make my day."

The list also said that if he could, he would sell his neighbor into sexual slavery in Mexico and that he is not "anti-social," he just doesn't like people.

Within hours of the Daily Press posting the unedited version of his blog on vvdailypress.com, there were 42 comments to McGlaughlin's Myspace page, all related to Bodhi Sherzer-Potter and Christopher Cody Thompson's death - all of them condeming his alleged actions.

He also uses "5150" in his display name, which is the penal code section for "a danger to self or others."

Under his interests, McGlaughlin said he is into "sex 420 fine cigars and fine liquor" - 420 being a popular reference to marijuana.

He also stated that his heroes are Sigmund Freud, Karl Jung and Vladamir Lennin.
