Burke

Ensign Burke was a male human who was a Starfleet officer on the station Starbase 17. He serves as a transporter chief

Around the 2260s, Admiral Gary Crockett ordered him to become a test subject for long distance transporting. However during the process, his brain got scrambled, somehow causing him to knock out the chief medical officer, the transporter chief on duty at the time and kill the entire crew of the USS Wasp.
