A Rock County jury finds a Janesville man guilty of first-degree intentional homicide.

24-year-old Julian Collazo was on trial this week for the second time in the 2017 stabbing death of 43-year-old Christine Scaccia-Lubeck.

Rock County Judge Barbara McCrory declared a mistrial in his first trial back in October of 2019 due to an uncooperative juror refusing to deliberate.

District Attorney David O’Leary pointed to DNA evidence linking Collazo to the murder, including the victim’s blood on his clothing and his DNA underneath her fingernails.

Defense attorney Jeff Jensen tried to argue that Collazo’s upset girlfriend Nicole Kazar actually committed the murder before the two stole Scaccia-Lubeck’s vehicle and fled the state.

The jury deliberated for less than two hours before returning the guilty verdict Wednesday evening.

The first-degree intentional homicide conviction brings Collazo a mandatory sentence of life in prison, but the two sides will argue about the possibility of parole at a sentencing hearing in October.
