Historians often despair of their ability to write histories of child murder,
because the crime was easy to commit and conceal. Even today, coroners can
determine only in rare instances whether a deceased infant or newborn was
suffocated or died of natural causes (Knight 1996: 441–44,
345–60). No reliable test can determine, once decomposition has begun,
whether a deceased newborn ever took a breath; and suffocation, unlike
strangulation, leaves no physical marks, unless excessive pressure is applied to
the face or lips. A murderer needed but a few moments to smother a child and
could claim that the child was stillborn, had been accidentally overlain, or had
died from natural causes. Unwanted pregnancies could be kept from public notice
with the help of family or friends, especially pregnancies that came to term in
late winter or early spring, when expectant mothers could live quietly out of
the public eye or stay wrapped in heavy clothing. In New England, a large
proportion of suspected neonaticides—nearly a quarter—occurred in
April or early May, “mud season” in the Yankee vernacular,when
people emerged from their long winter “hibernation.”
