A map of President Bush's motorcade route to Camp David was found last week when police searched the home of a teenager accused of stockpiling weapons and bomb-making materials, according to prosecutors.
Federal authorities have joined police in investigating Collin Matthew McKenzie-Gude, 18, who allegedly was storing the weapons and materials just outside Washington, D.C., at the Bethesda, Md., home where he lives with his parents.
MyFOXDC.com reports that Assistant State's Attorney Peter Feeney disclosed the discovery of the map of Camp David during a court hearing on Tuesday in Rockville, Md. The map was marked with the motorcade route to the secluded presidential compound in western Maryland, about an hour's drive from Washington.
When asked if McKenzie-Gude was planning to ambush the president, State's Attorney John McCarthy — the county's lead prosecutor — refused to comment, MyFOXDC reported.
Police also reportedly discovered range-finding binoculars, a CIA identification and a Geneva Convention ID, like ones given to contractors in Iraq.
Additionally, according to The Washington Post, investigators discovered documents on how to kill from a distance of 200 meters — a little more than two football fields.
The CIA and Defense Department have started their own investigations of McKenzie-Gude and an unnamed 17-year-old male, who also has been charged in the case. The FBI and ATF are reviewing the case but haven't launched its own investigation, sources tell FOX News.
The unnamed juvenile, while working as a police intern, allegedly took official stationery to help McKenzie-Gude obtain chemicals and police equipment, including bullet-resistant vests.
Police found four assault rifles, two shotguns, one handgun and ammunition for the weapons, along with "chemicals and components commonly used to manufacture homemade explosives" at McKenzie-Gude's home, according to a Montgomery County police news release.
Police said they also have uncovered a list of home addresses of faculty at the teenagers' school, St. John's College High School — McKenzie-Gude is a graduate — though no connection between the list and the weapons has been identified.
"We have found no further evidence regarding St. John's high school, so this is a very critical factor in this investigation to try to determine what the purpose was by these two young men by acquiring very dangerous weapons and chemicals," Montgomery County police spokeswoman Lucille Bauer said earlier this week.
The charges against McKenzie-Gude are mounting. After the initial charges of illegal weapons and explosives possession, police discovered a field where he allegedly set off bombs, leading to other charges.
And McKenzie-Gude, after learning that police were closing in on him last week, allegedly tried to take a car by force from a 78-year-old man at a nearby mall, leading to attempted carjacking and assault charges.
Court documents say McKenzie-Gude dropped his Blackberry in the victim's car, and it was later found by police. McKenzie-Gude is being held on $750,000 bail.
The juvenile charged in the case faces theft, computer misuse, and conspiracy charges. Police say he had worked as an intern at the county police department and swiped documents that allowed McKenzie-Gude to purchase the explosive chemicals, as well as police equipment including bullet-resistant vests and the false identification.
McKenzie-Gude's father, Joseph Lane Gude Jr., also is charged in the case. Police say he illegally bought firearms for his son.
