According to authorities, Kyliel Denzel Arceneaux approached Beckett outside the parking lot of a senior living complex and began pistol-whipping him after a brief conversation. They say Arceneaux then shot Beckett before stealing Beckett's car and running him over.
Police reported finding Beckett lying in the parking lot with gunshot wounds. He was later pronounced dead at the hospital.
Prosecutors said the unusually high bond amount was because of the nature of the crime and the fact that it was completely random.
Arceneaux is charged with capital murder and aggravated assault with a deadly weapon.
He was also charged with tampering with evidence after police said they found he had tried removing blood and fingerprints from the vehicle and had even thrown away a bloody shirt.
He is expected to be in court again in December.
