The family of the crazed ex-con accused of a deadly shooting spree aboard a Queens bus apologized yesterday to the loved ones of the victims.

“We are truly and deeply sorry to the families,” said a relative of alleged gunman Damel Burton who asked not to be named outside Queens Criminal Court.

Burton, 34, is accused of killing his girlfriend’s 18-year-old son, Keith Murrell, then boarding the Q111, where he shot passenger Marvin Gilkes dead and critically wounded another rider, Jojuan Lispey.

“The family is very upset, contrite and remorseful to the victims. They would like to say they’re sorry to the victims’ families,” echoed Anthony Rattoballi, Burton’s lawyer, who spoke on behalf of Burton’s grandmother, aunt, uncle and two cousins.
