Thankfully, Danny was able to track down his niece when he discovered he could find her whereabouts by tracking her phone.
Thinking the detective would chase after him, Wilder left Nicki in the car and ran into the deserted field.
However, Danny wasn’t willing to let him get away any longer and used his service weapon to shoot the murderer.
As the series has been on screen for 12 years it’s likely there will be a number of other blunders gone unnoticed by showrunners, who could be more focused on the stellar storylines.
Blue Bloods is available on NBC. A UK release date is yet to be announced.
