Through further investigation of the information gathered from the tipster, the Des Moines Police Department identified two people of interest.
Working with the Sea-Tac Police Department, Des Moines police arrested Threadgill and McMillon-Cooper on Tuesday night for investigation of homicide. On Thursday the pair was ordered to be held without bail.
“One of the suspects was arrested from his workplace and the other at her residence,” according to Des Moines police detective Mike Thomas.
Thomas said the information provided by the tipster "was very detailed."
According to Thomas, the pair had been on his radar for a while. "We’ve interviewed both of them in the past and early on. Obviously they didn’t admit any involvement at that time or it wouldn’t have taken that long.”
Of the two suspects, Thomas said, "I can say one of the people knew her (the victim) and one of them knew of her, but maybe not as well. '
The suspects were booked into the King County Jail will make their first court appearance Thursday.
Police said the Walstrand murder case is still an active investigation and they are looking into the possibility that others are involved.
