Police believe they've recovered the weapon used to kill a woman in southwest Sioux Falls.
The knife and gloves investigators think 41-year-old John Senn was wearing when he murdered 53-year-old Brenda Hansen were found in a gas station dumpster by detectives Thursday night. Police say they are items that could help build a stronger case against the suspected killer.
"They pretty much narrowed it down from the victim's home to where the suspect was found. They figured there wasn't a whole lot of time for him to go to a lot of different places," Sam Clemens with Sioux Falls Police said.
Sioux Falls Police found the knife by retracing the route they thought Senn could have taken following the stabbing. That's when they arrived here at the Kum and Go at 41st and Sertoma. When they searched through the dumpster that's when they found the weapon.
The knife found in the dumpster was a foldable pocket knife and the gloves had blood on them. The evidence will be sent to the crime lab for testing.
"Probably look at some DNA testing and see if the victim's blood was on that and then if there was any blood from the suspect that was either found on the knife or on the gloves," Clemens said.
When Senn was arrested investigators say he had some of Hansen's prescription Oxycontin pills, but they still aren't sure how the two knew each other.
But now that they have the suspected murder weapon they do believe it will help their case.
"It really just shores up a lot of loose ends. Especially once the testing is done if it in fact turns out to be his gloves and knife as we believe than it really eliminates a lot of different possibilities as to what may have taken place," Clemens said.
Senn is currently being held on a $1 million bond.
A memorial fund has been set up for Brenda Hansen's family at any Home Federal bank.
