When Stafford Township Police Lt. Allen Halliday, making his final 10-7 not long after noon on May 29, heard the voice on the other end of the radio, there’s little doubt he recognized it instantly.

“It is with great pleasure that today, May 29 … your son, badge 124, delivers your final call,” said Zachary Halliday, who radioed out to “all units in the field,” as his dad became visibly emotional.
