“Murdered,” Sandoval repeated hollowly from the depths of his chest. It was exactly what he’d been praying not to hear. What had he done to deserve this? How could this be happening to him again? It was incredible: only two murders in the last half-century, and both of them during the one-year tenure of Flaviano Sandoval, whose stomach fluttered at the idea of looking at a corpse. It was unbelievable, unfair, not to be borne.

However, once more he steeled himself to face the matter head-on, as the responsibilities of his position demanded. “What makes you think he was murdered?” He could hardly get the words out.

Bustamente bridled. “I don”t think, I know.” He crooked a bony finger at the police chief. “Come over here,” he commanded and led him to the sink. “Look at this.” When Sandoval realized he was looking at a man’s chest just sitting there in the sink like a slab of raw-hide, his insides started gurgling again.

Wordlessly, Bustamente stuck his finger into a dark hole not far from the middle of the slab. “You see?”

“From a bullet?” Sandoval asked. If he squeezed his eyelids together, leaving just a slit, he could see it without really seeing it.

“Without question.” He removed his finger. “You see how the borders of the perforation appear to have been eroded or eaten away? So that the hole is ‘cratered,’ as we might say?”

“Yes,” said Sandoval queasily, although all he could make out through his squint was a roundish hole with blackened edges. There was no denying, though, that it was the right size for a bullet hole. He had shot enough rabbits to know as much.

“This eroded area is what we refer to as an ‘abrasion collar,’ ” Bustamente continued, in the manner of a teacher talking to a not-too-bright pupil. “It is the result of scraping from the rotating motion of the bullet as it penetrates the skin. Being unique to gunshot wounds, it leaves no doubt as to the source of the penetration. Judging from the size of the hole, I would guess the bullet was. 32 caliber, but I leave that to the experts.”
