Monday, police told us they're following up on a number of tips, and asking area businesses to check their surveillance feeds for anything that could be helpful.
As for Kirkegaard's neighbors, this incident has many feeling uneasy. She lived on the 700 block of South Garfield Avenue in central Sioux Falls, right by Garfield Elementary.
Many people in the neighborhood have told me it's too dark here at night.
One person said it's very easy for someone to come in off of 12th Street and just disappear.
But Monday, they'll find out what the city plans to do about it. Streets in the Garfield neighborhood are lined with a lot of trees but not too many lights. And that's been a concern for neighbors.
Garfield Neighborhood Watch coordinator Jolynn Petersen said "keeping our neighborhood bright, making sure we've got the safety, you know, light up the night, you need to have that so you can see what's going on."
Eery two months Petersen brings her neighbors together to talk about their community.
"It's very important to know your neighbors, we're the eyes and ears of the neighborhood, and even with talking to the police they can't be everywhere at once and so they need our assistance," Petersen said.
This neighborhood is a place Petersen has called home since she was two years old.
"I have always loved it. You see the changes and the transitions but its a great place I've raised my kids here, my nieces and nephews live in the area and so it's a good place to be," Petersen said.
And soon, the city will begin to add more lighting, making it a brighter place to be.
"I wanted to have our neighborhood safe. I have kids who come home late at night and I want to make sure my kids are safe, and that way everybody is safe, and they have the lighting, the adequate lighting that we need," Petersen said.
There's a meeting tonight here at seven at St. John's American Lutheran Church at 13th and Western.
Neighbors will be able to express their concerns and find out about plans to increase street lighting in their area.
