A miscellaneous incident finally resolved. On August 25, 1990, a woman walking her dog in the woods near a lake on the outskirts of Seattle, Washington discovered the body of 17-year-old Michelle Koski. The young woman had been missing for five days. She was raped, strangled and finished off with a piece of concrete. On the spot the police found traces of DNA, but this one did not correspond to any known person in their files.
The file was finally reopened in 2005 by a retired detective with a cold case specialist (old unsolved court cases). However, it will be necessary to wait for the progress made in the comparison of DNA with genealogical databases to discover the identity of the murderer.
All this allowed a DNA specialist to orient himself towards the trail of two brothers. One of the two, Robert Brooks, was already in the system since he had been released from prison 4 months before the murder. Incarcerated for a minor offence, the man, who was 22 at the time, lived with his parents, a few steps from the Koski family home
The murderer who died in 2016
“We think Michelle met someone she knew who took her into the woods so they could drink. The person was probably planning on having sex and she didn’t want to. She probably tried to run away and he knocked her down and strangled her,” Snohomish County Sheriff’s Detective Jim Scharf said in 2012, as reported by Fox 13.
But Robert Brooks died in 2016, aged 49, of natural causes. A few days before being murdered, Michelle Koski had just celebrated her 17th birthday. “Every time she organized a birthday party, she fell ill she was so excited,” said the victim’s mother, Violent Simonson, relieved to know the truth today: “I thought I would take this mystery in my grave”.
