The family of a care home resident who tragically choked to death on a disinfectant wipe is seeking a DNA test on a single hair that was found stuck to the wipe. The hair, which was missed by the authorities, could potentially provide crucial evidence in bringing justice for Cheryl Yewdall, according to the family's lawyer. The DNA test on the strand of hair is seen as a promising avenue for uncovering the truth behind the incident.
