This study investigated whether DNA could be used as a means of protecting infants and children from physical abuse by determining the origin of the DNA gathered from the victims’ faces.
Abstract
The study investigated that when an individual hit a child whether some of that person’s DNA would be deposited onto the child’s skin. Results demonstrate that it is possible to swab for DNA from the faces of young children and infants in a way that is acceptable to children and families, while minimizing operator contamination. However, DNA obtained from the faces of children was mostly that of the subject and little DNA from caregivers was observed. The nondonor DNA that was collected was of insufficient quantity to identify the individual from which it originated. Although in adults it is recommended that gowns/scene suits, face masks/visors, and gloves be worn, this presents an impractical, frightening environment for the impressionable child, especially if the child is the victim of abuse. A distressed child is likely to push the operator away, and is almost certain to contaminate the swabs with which the operator is sampling. If the confidence or interest of the child is lost, then the technique will fail and further examinations may be inappropriate. Contamination from shed cells from the operator’s clothing is considered unlikely to be an issue; the need to wear gowns or suits is unnecessary. Similarly, the need for head protection is also considered unnecessary to protect against DNA contamination projected from the speaking operator’s mouth. The procedural solution was no mask, but to maintain the distance of 1 meter between the operator and the child. Further studies are needed to determine if DNA is actually transferred between individuals during forceful contact, and if so, how long it persists on the skin. Data were collected from several facial areas of 30 children aged 5 years and under. Figures, references
