Topic:  Pajamas

The pocket from Jeffrey MacDonald's pajama top was found at the feet of Colette on top of the flipped-up portion of a throw rug in the master bedroom.  The pocket was stained in six locations with Colette MacDonald's Type A blood. CID chemist Terry Laber analyzed the six Type A blood stains on the pocket.  
 
At the 1979 trial, Laber stated that "the pajama top was soaked with blood over the entire area where the pocket had been." In contrast to the pajama top, the pocket was lightly stained with blood, and all six stains were located on the outside or face of the pocket.  None of the stains, however, soaked through the double-layered fabric.

Laber also labeled each blood stain found the pocket with a letter designation.  The following are the blood stains that Laber identified, marked, and testified to at the 1979 trial:
 

Laber concluded that the totality of the evidence indicated that the pocket was stained with Colette's blood before the pocket was torn from the jacket.  The significance of Laber's analysis can be seen in the fact that Laber was one of the few government witnesses that Bernie Segal did not cross-examine.
