Chapter 1017 of the Detective Conan manga in Weekly Shonen Sunday issue 32 has announced another hiatus that is significantly longer than normal. However, this one is still only scheduled for 7 weeks, not nearly as long as the one we started this year with.
The end of the Policewomen Serial Murder Case included an announcement that Aoyama would be taking a break to gather materials for issues 33-39. The manga is scheduled to resume in Weekly Shonen Sunday issue 40.
