Where's KTAL's Todd Warren?

An e-mailer brought this to my attention and I just have to ask, Why is KTAL Met Rustin Duke pulling weekday duty and Where's Chief Met Todd Warren? Remember from a few weeks back the rumor of Warren "shopping around"?

Update: ATN has learned Todd is on vacation. Personally I'm glad this is the case. When KTAL changed staff a number of years ago I was glad Nexstar brought Todd back.
