Sounds like it's touch DNA that they're using to expand analysis into including familial markers which increase the risk of misidentification even further.
This risk will increase further as state and local law enforcement agencies begin to use Rapid DNA analyzers—portable machines that can process DNA in less than an hour. These machines will make it much easier for police to collect and analyze DNA on their own outside a lab. Currently, because forensic DNA analysis in a lab takes so long, we generally see its use limited to high-level felonies like rape and murder. However, Rapid DNA manufacturers are now encouraging local police agencies to analyze DNA found at the scene of low-level property crimes. This means much more DNA will be collected and stored, often in under-regulated local DNA databases. And, because most of the forensic DNA found at property crime scenes is likely to be touch DNA—this only increases the risk that people will be implicated in crimes they didn’t commit.
