After using a scanner at Northwood University in West Palm Beach to create $1,250 in counterfeit money, they bought a quarter-pound of marijuana from a 19-year-old Boca Raton drug dealer, police said.
But the dealer, realizing the money was fake, took an AK-47 assault rifle and ran out of his house, firing 21 rounds into a black Mustang and wounding two of its occupants, police said.
John Addison and Andrew Hernandez, both 18, remain in critical condition in Delray Medical Center after the Sunday shooting, the South Florida Sun-Sentinel reported.
Police arrested the alleged dealer, Thomas Fenech, and charged him with three counts of attempted murder.
Fenech has a criminal history that includes two arrests on drug charges in Pinellas County, police said.
