Fifty police officers lobbed tear gas into a second-story motel room early yesterday to rout two men suspected of a rampage of murder, abduction, rape and robbery across 100 miles of coastal South Carolina.

One of the two West Virginia men chose suicide rather than surrender, police said. The other gave up without resistance.

The storming of the Komo Mai Motel brought an end to eight hours of violence in which four persons were killed, including one of two women who were abducted and raped. The other woman was critically wounded.

At one point a 4-year-old girl, slightly wounded by a shell fragment, rode 4 1/2 miles on her bicycle to report that the marauders had killed her father, police said.

Police said Eugene E. Skaar, 40, of Huntington, W. Va., shot himself in the head after officers surrounded the motel shortly after midnight and demanded that the men give themselves up.

The other man, Ronald R. Woomer, 24, also of Huntington, was taken into custody. He will be arraigned on charges of murder and other crimes, according to Horry County Assistant Police Chief Gene Graham.

The wave of terror had begun about 4 p.m. Thursday when an elderly man was killed in the Colleton County town of Cottageville. About two hours later a man and a woman were fatally shot near Georgetown and then two female convenience store clerks were abducted, raped and shot.
