Apparently Walter needs to check the victim's anus to assess the degree of rigor mortis... or something like that. From season 4 episode 1, "Neither Here Nor There".
ASTRID: (into her audio/camera earpiece as she sets-up her equipment) Walter. Walter, are you there? Walter, hello? (in his lab, Bishop is fixing some popcorn and listening to loud music) Walter. Walter, can you hear me?
WALTER: (settles at his workstation to help remotely) I'm here. The microwave was causing a disturbance. I can hear you perfectly. You're as clear as a bell. How's the squelching?
ASTRID: It sounds great.
WALTER: (looks at the monitor with video feed from Astrid's headset) I'd like to see the body. Chop, chop. (about the nearby forensics technician) Don't let that ham-fist touch her.
ASTRID: (filtering Walter's message and relaying it to the technician) If you don't mind holding off for a moment, I'd just like to do a preliminary.
WALTER: (studying the monitor while munching on his snack) Burn mark like the other victims. Pupils are dilated. That looks like a hematoma on her right clavicle.
ASTRID: Yeah, and her right jaw.
WALTER: Rigidity indicates premature rigor mortis. I need to check her anus. Have that large lady there help you lift her.
ASTRID: (filtering Walter's message again and gingerly requesting) I'm going to -- I'm going to need to check her anus.
CSI TECH: (slowly. nodding) Okay.
ASTRID: Thank you.
