Sioux Falls Police say the man caught on surveillance video near Kari Kirkegaard’s home early Saturday morning is directly involved in the city's first homicide of the year.
Police released new pictures and details Thursday.
Authorities believe the man rode a bicycle to Kirkegaard's home between midnight Friday and sunrise Saturday morning. Police believe the man then took Kirkegaard's 1998 Ford Explorer for a ride but returned it to the neighborhood sometime early Saturday morning.
Authorities want to hear from anyone who happened to see the SUV driving around town Saturday morning before sunrise. It's dark blue and has a number 15 racing decal in the lower left rear window.
Investigators also want people in the area to be on the lookout for an abandoned bicycle.
