Common context
Intimate-partner violence
Typical marks
Asymmetric, fingertip-sized contusions
Caveat
May leave no external marks at all

Common questions

Why is the absence of visible neck marks not evidence that manual strangulation did not occur?+

Light or brief compression, application over clothing, or a delay between the assault and examination can all leave no visible bruising even when internal injury such as hyoid fracture or petechiae is present, so a clean external exam does not rule out strangulation.

How does the pattern of bruising help distinguish manual strangulation from other neck compression?+

Fingertip-sized, asymmetric contusions with a gap consistent with a thumb-and-fingers grip point to hands rather than a ligature, which instead tends to leave a continuous horizontal band; examiners map the bruise pattern against hand anatomy to support the distinction.
