ex-con interpreter delivers gibberish sign language at police press conference In Tampa

An American Sign Language interpreter has baffled the hearing impaired by delivering gibberish gestures during a crucial police press conference in the Tampa serial killer case.As Tampa police Chief Brian Dugan announced the arrest of Howell Donaldson Wednesday night, interpreter Derlyn Roberts was there beside him, making signs that made no sense.

State records reviewed by DailyMail.com show that 53-year-old Roberts, who also goes by the name Derlyn Glover, served a five-year prison sentence on a felony fraud conviction and was released in April of 2016. She also has prior convictions for grand theft and burglary.

'She sat up there and waved her arms like she was singing Jingle Bells,' Rachell Settambrino, who is deaf and teaches American Sign Language at the University of South Florida, told the Tampa Bay Times through an interpreter.LINK
