A veteran Tampa Police homicide detective is under a criminal federal investigation, according to a court document filed in the Julie Schenecker case.

That document called a notice of exculpatory information states "officer Eric Houston has been put on Notice by the Tampa Police Department that he is the subject of an active federal investigation... but no additional information is available at this time."

The notice was filed in Schenecker case on April 10. A TPD spokeswoman said Houston, 53, was placed on administrative duty when the U.S. Attorney's Office notified the department on April 3.

Houston was one of the homicide detectives who worked on the Schenecker investigation back in 2011.

The New Tampa mom is accused of killing her teenage children because they were "mouthy." Schenecker's trial is scheduled to begin on Monday.

A TPD spokeswoman said Houston played a minor role in the Schenecker investigation and wasn't expected to testify anyway.

Bay News 9 looked through the 24-year veteran homicide detective's personnel file on Wednesday that was filled with glowing reviews and awards. There was nothing negative found in the file.

TPD Chief Jane Castor fired Houston's wife, La Joyce Houston, in 2013 for allegedly using an inmate's food stamp card. Houston was a 16-year veteran of the department.

La Joyce Houston has been charged with grand theft and two counts of food stamp fraud. Her case is still pending in Hillsborough District Court. La Joyce Houston's attorney, Lyann Goudie, said as far as she knows the federal investigation into Eric Houston has nothing to do with his wife's case.
