A masked suspect accused of gunning down two bank employees inside a Kentucky branch is now facing federal charges after a wild, high-speed chase that ended in a crash, according to court documents. Brailen Weaver, 18, is accused of carrying out the April 30 attack at a US Bank branch in Berea, where authorities say he shot and killed two employees shortly after entering the building. According to an FBI affidavit, the suspect entered the bank around 1:57 p.m. and “immediately shot and killed a male victim” before fatally shooting a second employee, identified as a teller. Kentucky State Police later identified the victims as 35-year-old Breanna Edwards and 42-year-old Brian Switzer during a news conference.
