Last year he was named detective of the year, but now a 23-year veteran of the Metropolitan Police Department has pleaded guilty to secretly videotaping his adult stepdaughter while she was undressing.

Detective Keith Tabron pleaded guilty to multiple counts of video surveillance with prurient intent in July. According to prosecutors in the Prince George’s County State’s Attorney’s Office, Tabron videotaped his stepdaughter in the bathroom as she was getting in and out of the shower as well as in her bedroom as she was undressing.

Court records show Tabron was charged with 50 counts of secretly videotaping the victim over the course of nine months in 2011 and 2012. A spokesperson for the State’s Attorney’s Office said the victim was the daughter of Tabron’s estranged wife who lives out of state. The victim was staying at Tabron’s home because she had “fallen on hard times,” according to spokeswoman Gina Ford.

According to Ford, the victim realized she was being spied on when she noticed fresh paint in her bathroom. When she inspected the paint she found one of the cameras. The victim called a cousin who found the second camera in her bedroom. They traced the wires back to Tabron’s home office and called police.

Tabron has been suspended from the police force without pay, according to a spokesperson for D.C. police Chief Cathy Lanier.

Attempts to reach Tabron for comment were unsuccessful.

Tabron joined the force in 1990 and, according to a department press release, he was named 2nd District Detective of the Year in 2012 for his work getting a defendant to confess to 28 burglaries.

“Tabron used his excellent interviewing skills to bring these crimes to a closure," the program for the ceremony read.

Tabron was sentenced to 5 years suspended sentence and 5 years of probation. Ford says because Tabron had no previous criminal record prosecutors did not request that he be required to register as a sex offender. Surveillance with prurient interest is a registerable offense in Maryland.
