The death of a congressional aide to U.S. Rep. Dan Lipinski who was found in her Oak Lawn home early Tuesday morning has been ruled a homicide by the Cook County medical examiner’s office.

Marianne L. Viverito, of the 5100 block of W. 105th Place died of "multiple stab and incised wounds," the medical examiner’s office determined Wednesday.

Police said in a press release that Viverito, the daughter of Stickney Township supervisor and former state Sen. Louis S. Viverito, may have been the victim of a domestic altercation.

Oak Lawn police, who are investigating the homicide in coordination with the South Suburban Major Crimes Task Force, have yet to announce an arrest or any charges in the case.

In a statement released Tuesday, police said they received a request from an out-of-state police department to conduct a well-being check at Viverito’s home and upon arrival around 3:15 a.m. Tuesday found blood on the ground and in the residence.

Officers found Viverito’s body in the basement of the home, police said.

Oak Creek Police Department in Wisconsin, which village officials identified as the out-of-state agency that contacted local police, would say only that they contacted Oak Lawn after responding to a car crash.

"There was an incident of a car striking a telephone pole," Lt. Randall Knitter of the Oak Creek Police Department said. "As a result, it led to the Oak Lawn investigation. For the rest, you’ll need to talk to Oak Lawn."

Oak Lawn Police said Tuesday that they have a suspect in the case, but have not responded to media requests Wednesday.

Viverito was a divorced mother of two adult sons who had raised them alone from the time they were young children, her father said.

He said she was a graduate of Queen of Peace High School in Burbank and Fox College, where she studied business.

Viverito had worked out of Lipinski’s Oak Lawn office since February 2007, and before that was employed by the Cook County Circuit Court, her father said.

She also served as a Worth Township trustee from 2012 to 2013.

A visitation for Viverito will be held Friday from 1 p.m. to 9 p.m. at Lawn Funeral Home, 7909 State Road in Burbank.

Her funeral mass is scheduled for the following day at 10:30 a.m. at St. Albert the Great Church, 5555 State Road in Burbank, with burial to follow at Holy Sepulchre Cemetery in Alsip, 6001 W. 111th St.
