The Manhattan jurors weighing the fate of the man who admits kidnapping and murdering ­6-year-old Etan Patz in 1979 told a judge Wednesday that they were deadlocked.

“We, the jury, after 10 days of deliberations, want to let the court know we are unable to reach a unanimous decision,” the jurors wrote in a note delivered to
Manhattan Supreme Court Justice Maxwell Wiley just before 12:30 p.m.

But the judge encouraged the panel of ​seven men and ​five women to go back and try harder.

“Given nature of this case, I don’t think you’ve been considering this case long enough to conclude you cannot reach a verdict,” the judge told them over the objections of the defense lawyer, who insisted that a mistrial be declared.

The jury will next listen to readbacks of the summations in the case.

Etan vanished from a Soho street on May 25, 1979. It was the first time that the boy’s parents had let him walk alone to the school-bus stop.

​The defendant, Pedro ​Hernandez, 54, worked as a stock clerk at the bodega next to the stop on the day the boy disappeared, but was not a suspect until 2012.

Authorities picked him up after his brother-in-law called in a tip that Hernandez had confessed to killing a child.
