skin was recovered from beneath one of Colette's fingernails, although this evidence was later lost. Bloodstained splinters likely sourcing from the section of lumber recovered close to the back door of the apartment were recovered from all three bedrooms of the apartment, but not the room where MacDonald claimed to have been attacked. No blood or fingerprints were found on either telephone MacDonald claimed he had used to call for help after checking each member of his family and attempting to resuscitate them. Furthermore, the bloodstained tip of a surgical glove was also found beneath the headboard where the blood inscription was written; this glove was identical in composition to a medical supply MacDonald invariably kept in the family kitchen. Although it had rained on the night of February 16–17 and MacDonald also specifically claimed the female intruder's boots were "all wet", with rainwater "just dripping off them", the sole footprint observed at the scene was a bloody bare footprint located in Kristen's bedroom, leading from the child's bed in the direction of the doorway. Forensic analysis By mid-March, the CID had obtained the results of forensic testing of the blood, hair, and fiber samples within 544 Castle Drive that contradicted MacDonald's accounts of his movements and further convinced investigators of his guilt. For example, Kimberley's blood was also found on his pajama top, even though MacDonald had claimed he was not wearing this garment while in her room attempting resuscitation. MacDonald's own blood was located in significant quantities in only two locations: in front of the kitchen cabinet containing rubber gloves, and upon the right side of a hallway bathroom sink. Investigators also questioned why Colette's blood was found in Kristen's room, although all three victims were found in separate rooms, suggesting they had been attacked separately. Moreover, although blood evidence indicated Kimberley had been attacked as she entered the master bedroom, investigators questioned why home intruders would bother to carry her back to her bedroom to continue their attack. The four members of the MacDonald family had different blood types: a statistical anomaly that assisted investigators in determining the movements of each member of the household and their subsequent theory as to a likely scenario of the unfolding events. Upon the assumption the four individuals discovered by responding military police were the only four people in the house in the early hours of February 17, investigators were able
