Deputies have arrested a third man suspected in an Altamonte Springs murder that happened in 2012.

Authorities arrested 22-year-old Keyon Brown on Tuesday and charged him with first-degree murder and robbery. Authorities have been looking for Brown since October of 2012, and say they have spent an entire year building a case against him for his involvement in the murder.

Seminlole County investigators say he was driving the get-away vehicle that transported the two other suspects from the scene.

Deputies say Robert Turner and Darius Conyers went into an Altamonte Springs home on Pine Street where they tried to rob two men inside before fatally shooting one of the victims in the head and fleeing in a vehicle driven by Brown.

The victim, 36-year-old Brent Roux, later died from those injuries.

Deputies also arrested Turner last year, along with Conyers, and charged both with first-degree murder in the case. 

All three suspects are now in jail on no bond.
