Man pleads guilty to Madison sex assaults, burglary

  • 0

A 28-year-old Madison man pleaded guilty Monday to sex assault and burglary charges for a string of incidents in September 2019.

Luis Ruiz-Ugalde pleaded guilty to felony attempted second-degree sex assault of a child and misdemeanor fourth-degree sexual assault, as well as felony burglary. The first stems from an incident on Sept. 22, 2019, on a Madison Metro bus when he groped a 13-year-old girl, the second for groping a woman outside her Near East Side home two days before.

In the burglary case, he broke into an apartment near the UW-Madison campus in the early morning hours of Sept. 17, 2019, touched the bedding where a woman was sleeping and stole clothing.

A few days after the crimes, then-Madison Police Chief Mike Koval said a photo taken by an 11-year-old friend of the 13-year-old victim was crucial to arresting Ruiz-Ugalde, who was then homeless.

As part of the plea deal, charges of second-degree sexual assault of a child, lewd and lascivious behavior and attempted second-degree sexual assault with the use of force were dismissed. An April 29 felony charge of having illegal materials with him in the Dane County Jail — specifically, a small amount of cocaine — was also dismissed but can be considered at sentencing, scheduled for Aug. 2.

Ruiz-Ugalde faces up to 40 years in prison on the attempted sex assault charge alone.

When initially arrested, he was held on an immigration detainer, which U.S. Immigration and Customs Enforcement places on those suspected of being in the country illegally as part of a deportation proceeding.

Ruiz-Ugalde had been scheduled to stand trial starting June 1, when his trial would have been the first serious felony case heard by a Dane County jury since the start of the COVID-19 outbreak in March 2020. With his guilty pleas, the trial is canceled.
