Original Story:
The investigation into a missing woman last seen at a Seattle Mariners game has resulted in the recovery of an unidentified body in Renton, according to .
The King County Medical Examiner’s Office has yet to confirm the identity of the deceased and the cause and manner of death.
Suspect in woman鈥檚 disappearance from Mariners game later allegedly attacked her son
Leticia Martinez-Cosman, 58, was last seen at a Mariners game at T-Mobile Park March 31 with Brett Gitchel, 46. She was reported missing by a family member on April 2.
Gitchel was arrested for allegedly trying to kill Patrick Cosman, Leticia’s son, around April 2. The King County Prosecutor鈥檚 Office stated Gitchel鈥檚 cell records 鈥 using cell tower data to triangulate the location and position of a phone鈥檚 location 鈥 identified that Gitchel鈥檚 cell phone activity is consistent with him being at Martinez-Cosman鈥檚 home at 2 a.m. April 2, the time her son Patrick was kidnapped.
In an interview with detectives, Patrick recounted being awoken by the sound of a man knocking on his bedroom door on April 2. He was not able to articulate who the man was but described his attacker as being in his 30s or 40s with facial hair and glasses.
The man told him that his mother had been in an accident and that he was going to take him to see her at the hospital. Patrick got into a car with him and 鈥渄rove around for what seemed like hours.鈥
The son told detectives that the man then got into the seat in the car behind him and tried to 鈥渒ill him by smothering or strangling him.鈥 The son said he was able to fight the man off, even managing to bite his hand.

The son then reportedly escaped from the car and called 911, before going into a neighboring yard and hiding in the bushes.
When Gitchel was brought in by police, he had 鈥渘umerous visible injuries on his body, including many cuts and scrapes on his hands,鈥 as well as bruises on his face, arms, and body, according to an interview with police two days later.
Gitchel has since been charged with first-degree kidnapping, unlawful possession of a firearm, first-degree theft, and second-degree arson. The arson charge is related to Seattle firefighters discovering a vehicle 鈥渇ully engulfed鈥 in flames less than two miles from T-Mobile Park on April 2. The vehicle, a 2016 Honda CRV, was identified as belonging to Martinez-Cosman and was determined to have been torched using an accelerant.

“Within a three day period, Brett Gitchel was the last person to be seen with Leticia Martinez-Cosman. Brett Gitchel would drive Leticia’s vehicle to a remote area outside Seattle for a short period of time the next day, kidnap and attempt to kill her son and burn Leticia’s vehicle,” court documents said.
Prosecutors said Gitchel was pinged through cell phone records at 3400 Talbot Rd S in Renton, around the same time and location the son was choked.
