Sitting in the office of the Qianjin District Criminal Police Team, Jiang Yuan meticulously compared the footprint impressions of Bai Yuequn with the bloody footprints found at the crime scene, examining them over and over.
The trouble with footprints is that they cannot be used to identify a suspect on a one-to-one basis. They can come incredibly close, but they cannot offer certainty.
Otherwise, if they were like fingerprints, they could be used as definitive evidence for prosecution.
Barefoot prints could be considered as unique as fingerprints, but unfortunately, they are usually not available.
After all, murderers seldom kill barefoot.
Even though it's not possible to be 100% certain, from Jiang Yuan's perspective, the degree of overlap was basically enough to confirm Bai Yuequn's status as a suspect.
If the resemblance was this close and he wasn't the killer, then it would just add another layer of coincidence.
