Police in West Palm Beach described Javier Burgos, 53, of Greenacres, Fla., as armed and dangerous, the South Florida Sun-Sentinel reported. His car was described as a silver 2010 Toyota.
The bodies of Ted Orama and Christopher Marshall, both believed to be in their 50s, were found at 6 a.m. Wednesday at Dreyfoos, a magnet school serving Palm Beach County.
The cause of death has not been released. Police Capt. David Bernhardt said Wednesday investigators were trying to determine how the two men died.
Dreyfoos was renamed in honor of Alexander W. Dreyfoos Jr., who gave $1 million dollars in 1997. It has been ranked as one of the country's top public high schools.
The school year ended June 6 and nothing was scheduled for Wednesday, officials said.
