Third Circuit Judge Michael Hutchings sifted through 129 separate exhibits Friday afternoon in preparation for the decision he'll make about the fate of Sam Kas-tanis.

After sitting through nine days of testimony - unusually long for a preliminary hearing - Hutch-ings said he hopes to decide Monday whether he's heard enough evidence to order Kastanis to stand trial on four counts of capital murder in the deaths of his wife and three children.The judge will give prosecution and defense attorneys an hour each to wrap up their case on Monday.

The final testimony came Friday from Dr. Todd Grey, who explained each of the many grotesque wounds the children - still in their pajamas - received on the morning of Nov. 17, 1991.

- The youngest victim, 6-year-old Christine Kastanis, was hit over the head between four and six times, probably with a hammer, the chief medical examiner testified. The blows came so hard they caused skull fractures.

She was also stabbed five times - three times to the chest, once to her back and across her throat. Christine also had cuts or defensive wounds on her left hand, indicating she had tried to block the attacker's blows, Grey said.

- The attacker slashed 11-year-old Melissa's throat so deep that it severed her windpipe. She was stabbed three times in her upper chest and once in her back. Her skull was "extensively fractured" when she was hit as many as six times with a hammer.

Melissa, too, suffered defensive wounds on her left hand and left leg trying to ward off the attacker. Grey said the wound on her leg was likely received while trying to fend off a blow while she was lying down.

The injuries the two girls received would have been extremely painful, particularly on the wounds where the attacker cut through bone, he said.

- Clint Kastanis, 7, received the most injuries - 23.

He was stabbed at least 15 times and received at least five blows to the head, some of which fractured his skull. At least four of the stab wounds would alone have caused his death, assistant medical examiner Edward Leis earlier testified.

As his sisters, Clinton also received defensive wounds on his hands from the hammer and knife. One of his fingers was nearly amputated during the attack, Leis said.

Blood-spatter expert Rod Englert earlier testified he believes Clinton was first attacked in a downstairs bedroom with the other two girls but escaped and ran upstairs, where he was killed in a bathroom.

- Unlike the children, Margaret Kastanis, 39, was not bludgeoned with a hammer. She received four stab wounds to the chest - one was 4 inches deep and another 5 inches. One was 5/8-inch deep while the other was superficial. She also received defensive wounds on her hands, Leis said.

Defense attorney Ron Yengich, however, contends those defensive wounds could actually be offensive wounds, which would support his client's theory that Margaret killed the children and then stabbed herself.

Yengich asked Leis Friday if he had ever been asked to compare similarities and differences between the way the children died and the way Margaret did. Leis admitted he had not.

In response to a another Yengich question, Leis said he was not asked to take any samples of blood from the skin of the four bodies' so the blood could be typed. He did, however, take fingernail samples, but no evidence was presented about whether the nails were tested for blood or hair samples.

Kastanis told police he went outside to an unattached garage between 8:30 and 9 that morning and returned to discover his slain family about 10:45 a.m. Leis testified the deaths occurred between 8:30 and 10:15 a.m.
