Jonathan stops moving and pauses in his dictation, his mind slowly comprehending what he has just felt. Realization slowly setting in, Jonathan croaks for the recorder, "A small movement is detected in the victim's intestinal cavity. Mayhap a parasite similar to the John Doe reported earlier. I am going to open up the lower intestines to get a look at it..."
OOC: Is there a basin or tub nearby? If there is a parasite, Jonathan would think to remove it and deposit in a secure (deep) reservoir.
"I think we have a live one here, Marcus." Jonathan reaches for a pair of heavy forceps. Holding the forceps in his left hand and a scalpel in his right, Jonathan probes the man's intestines, seeking to gently clamp the parasite while cutting away any intervening viscera with the scalpel.
