Jurors shown Kairissa's blood-stained shirt, crib mattress and drywall

Defense attorneys for a Mt. Juliet pediatrician have argued that the injuries responsible for the death of a 4-year-old girl adopted from China could have been inflicted the girl's adoptive father, according to NewsChannel 5 WTVF-TV.

The argument came Wednesday in day two of Dr. Deborah Mark's trial for homicide in Kairissa Mark's death.

Steven Mark was alone with Kairissa for a period of time the night before the child was hospitalized. However, the pediatrician told investigators she's never seen her husband hurt the child.

Prosecutors showed the jury several pieces of evidence Wednesday, including drywall and a crib mattress from Kairissa's room.

Early in the afternoon jurors were shown a cut-out of the drywall from Kairissa's room with blood on it. A Tennessee Bureau of Investigation forensic scientist said the blood belonged to Kairissa.

In a recorded interview played for the jury Tuesday, Dr. Mark admitted she flung the child onto a mattress, but the child's head hit a wall. Investigators also said they found blood on the crib mattress.

They jury was shown a small blood-stained shirt, which police said came from the sink in the Mark home.
