A thief who tried to avoid identification by going shoeless during some Fort Worth-area holdups must serve 35 years in prison.
Detectives said 21-year-old Johnny Lee Britt thought he could elude police by not leaving shoe prints.
Prosecutor Lisa Callaghan said "somebody had been watching too much CSI."
Britt pleaded guilty and was sentenced Wednesday over six aggravated robberies during 2008.
The Fort Worth Star-Telegram reported Thursday that masked robbers shed their shoes and opted for white crew socks during some of the crimes.
Nobody was hurt during the robberies that mainly targeted restaurants and retail stores.
Callaghan, who referred to the CBS television show "CSI: Crime Scene Investigation," said the shoeless aspect was the connecting factor in some cases.
She declined to provide more details on how Britt was identified, since a co-defendant awaits trial.
