Higgs has been arrested and charged with first-degree murder.
According to a police report, neighbors watched in horror as Higgs stabbed Brown several times with a kitchen knife in the hallway at Inland Towers Apartment. Higgs, 53, then fled the scene but was captured a short time later.
Police believe the two men knew each other for a long time and had an intimate relationship for the past seven or eight years before brown broke it off for unknown reasons. Brown, a 54-year-old teacher at North Miami High School, began receiving threatening E-mails at work and Higgs also sent his angry letters to the Miami-Dade County School Board.
Police believe all Higgs wanted was an explanation for the break-up and he waited in the hallway at brown's apartment to get it.
