Costigan mentally took note of the method that the attacker used. Partially it might be useful in finding the perpetrator, but he was also interested in knowing how Bakura could be stopped when push inevitably came to shove and they found themselves on opposite sides. It was something the Bostonian really didn't want. They would both be foolish to think it never would though.

The undercover followed Bakura down the hall and into the other room without comment, watching and taking everything in like he usually did. It was interesting to see a man who could bandage his own wounds. Costigan might have thought military if Bakura wasn't.. well, how he was.

"There are no records. You know that as well as I do. Have people seen him? Maybe. You want to make a public post asking about it?" It was a genuine question. He got the impression Bakura would want to leave his murder on the down low. If not, that made both their jobs easier. "Otherwise, we look the old fashioned way and ask around in quiet circles."
