A 30-year-old woman was shot to death at a home on Wausau’s west side early Sunday and police have arrested one man in connection with the death.

The shooting was reported at 2:37 a.m. Sunday in the 1300 block of North 9th Avenue. Officers responded to find the woman dead of an apparent gunshot wound, according to a Wausau Police Department release issued Sunday afternoon.

Umberto N. Lo, 24, was arrested at the scene and was transported to the Marathon County jail. Police say Lo and the victim knew one another.

Lo has a lengthy recent criminal record and has been charged in five separate felony cases from 2020-2021, all of which are pending. Open charges include strangulation/suffocation, disorderly conduct-domestic abuse, battery and multiple instances of bail jumping. In the most recent case, filed March 8, Lo faced four counts of bail jumping and was released March 10 with a no-contact order after posting a $2,000 cash bond. It is unclear whether the victim in the prior cases is the same woman who was allegedly shot and killed on Sunday.

A homicide investigation is underway, spearheaded by the Wausau Police Department and the Wisconsin State Crime Laboratory.

If probable cause is found, an initial appearance will be scheduled for a later date. The name of the victim is being withheld pending notification of relatives.

“Our thoughts and prayers are with the victim’s family and others impacted by her death,” said Wausau Police Capt. Benjamin Graham, in a news release.
