A new law went into effect on Jan. 1 in Michigan. It ordered everyone convicted of a felony or sex-related misdemeanor in Michigan to give authorities a sample of their DNA. This would be very helpful to investigators -- if everything were in place to carry it out.
The samples -- as many as 50,000 this year alone, Michigan State Police say -- would join hundreds of thousands of others in a searchable national database to help detectives chase down criminals based on the DNA evidence they often leave behind.
