Brett Peter Cowan (born 18 September 1969) is an Australian murderer and sex offender who was convicted of the murder of Daniel Morcombe, who disappeared from the Sunshine Coast on 7 December 2003.
His abduction led to an eight-year investigation involving various suspects, until an undercover police sting in August 2011 revealed Cowan as the perpetrator.
He was charged with the murder that same month and Morcombe's remains were discovered days later on 17 August.
Cowan was sentenced to life imprisonment, (being eligible for parole in 2031) on 13 March 2014 in a trial that attracted worldwide attention.
Cowan had two previous convictions for sexually abusing children, the earliest dating back to 1987.The investigation into Morcombe's disappearance became Queensland's highest profile crime case in the state's history.
