On April 22, 1979, FBI spokesmen announced their search for 34-year-old Lawrence Dalton, sought on murder charges after a woman's corpse was unearthed near Kenosha, Wisconsin, in front of a house which Dalton had occupied from March 1977 through February 1978. The victim was identified as Blanchie Penna, 25, missing from Racine, Wisconsin, and Dalton was also sought in connection with the murder of 12-year-old Lisa Slusser, slain in Waukegan, Illinois, during 1977. The fugitive had earlier been charged with rape , deviate sexual assault and taking indecent liberties with a child, following an incident in Brooklyn, where a 14-year-old girl accused Dalton of holding her hostage over a period of four months. Dalton's wife, Karen, and a female acquaintance named Barbara Filipski were also arrested in that case, charged with sexually abusing the girl. On April 23, Dalton was arrested in Cleveland and held for questioning on two counts of murder. (Further inquiries concerned a "Jane Doe" victim found in Lake County, Illinois, in the summer of 1978.) Formally charged with the Penna murder on the day of his arrest, Dalton waived extradition to Waukegan, where authorities placed the number of his homicides at four and counting.
