We found some blood on a knife! Whose blood is it? The girls are learning how scientists can use blood typing to narrow down our list of suspects. @scienceworldca #GirlsandSTEAM #CBRoutreach #GeneskoolCBR #bloodtype #ABO 
Hmm, looks like there were 2 different blood types on the knife...it's Kyle and the killer!
Is the killer Beth or Jon? The blood on the knife matches both of them...so who did it? Wait, we have new evidence--DNA!
