The American Journal of Forensic Medicine and Pathology: March 2001 - Volume 22 - Issue 1 - p 33-37 Buy Abstract The first reported case of simultaneous sudden infant death syndrome (SSIDS) in Allegheny County, Pennsylvania, occurred on February 27, 1998. Two-month-old black fraternal twin girls were both found dead in their crib at the same time. After an in-depth death scene investigation, police investigation, toxicologic analysis, and complete autopsies, a specific cause of death could not be identified. The deaths of the two girls were therefore ruled simultaneous sudden infant death syndrome. © 2001 Lippincott Williams & Wilkins, Inc.
