Ant bite artifacts in a case of hanging

J Forensic Sci. 2024 Feb 20. doi: 10.1111/1556-4029.15494. Online ahead of print.ABSTRACTArtifacts produced by postmortem animal scavenging are commonly encountered at autopsy. Knowledge of the pattern of artifacts produced by postmortem animal scavenging is essential for the correct interpretation of the autopsy finding. In household deaths, such artifacts are usually caused by domestic animals and by small insects such as flies, ants, beetles, etc. Ants are one of the early scavengers which feed on the dead bodies. The artifacts produced by the postmortem ant activity are usually superficial and non-bleeding type. Rarely, in the congested body regions and areas of marked hypostasis, postmortem bleeding artifacts due to ant bites are possible. In the reported case of hanging, such postmortem bleeding artifacts were present over both the legs, predominantly over the left leg. Typical ant bite lesions in the form of superficial excoriations were also present over the peri-ligature area, over and around both nipples and over the lower part of the abdomen. Morphologically, postmortem bleeding artifacts produced by ant bites exhibit four patterns: droplet pattern, stripe pattern, pool pattern, and mixed pattern. In this case, a mixed pattern (droplet pattern and stripe pattern) of postmortem bleeding artifacts was observed. The presence of postmortem bleeding artifacts over the lower limbs was attributed to the pooling of the blood due to suspension of the body, followed by passi...
