A Bronx man has been sentenced to life in prison — plus 34 years — for killing two livery cab drivers in separate 2014 carjackings.

Federal prosecutors say Tyrone Felder was sentenced on Wednesday after a jury found him guilty in September.

In the first incident, prosecutors say Felder and three other men carjacked a cab driven by Maodo Kane. They say Felder shot Kane in the back of his head and then used the stolen cab to commit gunpoint robberies of businesses in Yonkers.

Two weeks later, prosecutors say the same crew carjacked a livery car driven by Aboubacar Bah in the Bronx. When the driver resisted, prosecutors say Felder shot him in the head, killing him. They then abandoned the vehicle after it crashed into parked cars.

Felder's co-defendants have pleaded guilty to participating in the carjackings and await sentencing.

In pronouncing Felder's sentence, the judge said he was "astonished by the audacity and brutality" of Felder's crimes.
