Eugene Zapata, 67, was arrested without incident on Monday in the disappearance of Jean Zapata, who vanished on Oct. 11, 1976 after making breakfast and sending her children to school.

The 26-page criminal complaint contains no confession, but presents a set of circumstances alleging that Eugene Zapata knows how his estranged wife disappeared.

The complaint details the problems with the couple's marriage, an obsessive diary Eugene Zapata kept of his then estranged wife's travels around Madison and information about the findings of corpse-sniffing dogs used by police since the case was reopened in 2004.

``We knew that his storage locker in Sun Prairie had been cleaned out, dumped out the contents and we knew that canines indicated the presence of decomposing or decomposed human flesh at that storage locker,'' said Madison Police Capt. Tom Snyder said.

Hurley said the criminal complaint doesn't contain anything new and that the diary ``seems to be a journal of evidence of fault in a divorce'' at a time when Wisconsin did not have no-fault divorce.

Zapata said during an interview last year with police that the evidence found by then was pointing authorities in his direction, according to the complaint.

According to the complaint, Jean Zapata was upset with her husband for submitting photos of her to a swingers magazine so she filed for divorce and later began a relationship with another man, which Zapata monitored in his diary.

After the case was reopened, Zapata traveled to Wisconsin last year, and on April 13, 2005 he called the Juneau County Solid Waste Landfill near Mauston, according to he complaint.

Police later discovered he had visited the landfill to drop off items weighing about 60 pounds, and the dogs found the odor of human remains in the trunk of a car he rented, the complaint said.
