The head of the FBI's Dallas office is planning to retire.
Robert E. Casey will leave the bureau April 30 after five years as the Dallas FBI's special agent in charge. An FBI spokeswoman said Monday that the 54-year-old Casey is taking a job in the private sector, but declined to say where.
Casey was appointed to head the Dallas field office in May 2006. He joined the FBI in September 1986 and worked in field offices in Phoenix, Chicago and Miami.
During Casey's tenure, agents investigated and arrested a Jordanian man who thought he was plotting to blow up a 60-story office tower in downtown Dallas. Hosam Smadi was eventually sentenced to 24 years in prison.
Casey declined to comment on his departure.
