Ruth J. Bresnahan, an 83-year-old female from Milwaukee, Wisconsin, died on January 4, 1988, in what became part of a frightening cluster of attacks against elderly Milwaukee-area residents inside their homes. Online records identify her birth date as April 2, 1904, and her death date as January 4, 1988. Her death was later treated not as an isolated tragedy, but as one piece of a series of residential burglaries and killings that unfolded across Milwaukee County in the winter of 1987 and
1988.
According to the appellate record in State v. Wirth, Bresnahan was killed during the burglary of her residence. She died from asphyxia caused by crushing injuries to her neck. Her bedrooms had been ransacked, and money was missing from a small purse she reportedly kept pinned to her undergarments. Investigators also found a blood-stained stuffed toy donkey on the sofa inside the home. The stain was described as moist and damp, and later testing showed the blood was not Bresnahan's.
The circumstances suggested that whoever entered Bresnahan's home may not have been a complete stranger to her. Testimony later described her as security conscious; she kept her doors locked and would not open them for someone she did not know. A neighbor who visited her only hours before the killing said she followed her usual routine of checking through the window before opening both the inner and outer doors, then locked them after the visitor left. There was no forced entry reported at the homicide scene. That detail became significant because Robert J. Wirth, the man ultimately convicted in connection with her death, had painted Bresnahan's home approximately five months before she was killed.
Bresnahan's killing was followed by more violence. On January 11, 1988, Louis and Lillian Buchta were killed and their home was burglarized. Their house was ransacked, Lillian Buchta was strangled, and Louis Buchta was killed by repeated blows to the head. Ten days later, Eva Holman was murdered and her residence was burglarized; money and jewelry were missing, and her injuries were described as similar to those suffered by Bresnahan and Lillian Buchta. The pattern that emerged was one of elderly victims attacked in their homes while their residences were searched for valuables.
Robert J. Wirth became the central suspect. Investigators connected him to Bresnahan's murder through DNA testing that compared his blood to the blood found on the stuffed toy donkey in her home. The case is noted in online forensic-study material as an early use of DNA evidence in Milwaukee County. Other evidence tied Wirth to the broader series: he was seen near the Buchta residence around the time of those killings, and witnesses placed him near homes in Holman's neighborhood on the day she died. In one account, he tried to push into a nearby home but left after realizing a man was present inside. In another, he went to a different home nearby and tried the doors while claiming to be looking for directions.
The prosecution also presented evidence of other burglaries and attempted entries. Before Bresnahan's death, Karl Hoese's home was burglarized on December 14, 1987, and Hoese later identified Wirth as the man he found inside. Hoese said the intruder beat and kicked him until he lost consciousness. On January 2, 1988, two days before Bresnahan was killed, Robert McGuff identified Wirth as the man who entered his trailer home late at night, threatened him with a small pocket knife, and struggled with him before being kicked out the door.
A jailhouse informant also became part of the investigation. The informant, who was housed with Wirth at the House of Correction, told authorities that Wirth said if people were home when he burglarized houses, he killed them. The informant further claimed Wirth talked about using city buses to select homes to burglarize and leaving crime areas by taxi afterward. Detectives checked some details, including that Bresnahan lived close to a bus route and that Wirth had used a taxi in connection with the area of another killing.
Wirth was charged in connection with the deaths of four elderly Milwaukee County residents: Ruth Bresnahan, Louis Buchta, Lillian Buchta, and Eva Holman. He was convicted of four counts of first-degree murder and five counts of burglary. His appeal challenged, among other things, the search warrant that allowed investigators to seize his blood for DNA comparison, but the Wisconsin Court of Appeals rejected his arguments and affirmed the conviction.
For Bresnahan's family, the case ended in court with Wirth's conviction and sentencing. Online archival photo captions from the 1991 proceedings describe him as being sentenced to four life terms, and another online crime reference lists his punishment as four consecutive life terms plus an additional 20 years in prison. The available online information identifies Wirth as the convicted offender in Bresnahan's death and does not point to any other charged suspect in her killing.
