Ooh la la. A French thief who planted a kiss on the cheek of his victim has been caught thanks to his slobber. Yep, DNA is a bitch. Pierre and his sidekick followed an employee of a jewelry store home, tied her up, gagged her and poured petrol over her head until she revealed the codes to the stores alarm system and safes. One of the dudes then went and robbed the store while the other one watched over the terrified woman. When the job was completed Pierre untied the woman and gave her a kiss on the cheek. Poor Pierre. His DNA was registered on the national genetic database.
