Minneapolis police announced Tuesday that a $60,000 reward is being offered for information that leads to the arrest and conviction of Terrell Mayes' killer.
Terrell, 3, was fatally shot inside his home on the 2600 block of Colfax Ave North the day after Christmas in 2011.
Terrell and his brothers ran for safety in an upstairs closet as gunfire erupted outside their home, the Star Tribune reported. Terrell was struck in the head by a bullet as he climbed the stars and died the next day.
Police are still looking for the person responsible.
A billboard campaign will also be launched to help find a suspect.
Anyone with information related to the case is asked to contact the Minnesota Bureau of Criminal Apprehension's Cold Case Unit at 877-996-6222 or 651-793-7000, or email to email@example.com.
