Washington Woman Last Seen Alive At MLB Game With Man She Met At Costco Accused Of Strangling Her Special Needs Son: Cops

Seattle police are holding a suspect in the possible killing of a fan he escorted from a major league baseball game.

Leticia Martinez-Cosman, 58, was last seen alive at the Cleveland-Seattle game Friday, March 31.

A photo posted by the Seattle Police Department shows her in the stands next to Brett Gitchel, 46. Gitchel now is charged with attempted murder, first-degree kidnapping, assault, theft and firearms charges.

KIRO-TV reports Gitchel also is accused of kidnapping Martinez-Cosman's son, who is described as a adult with special needs.

The son told police that Gitchel claimed Martinez-Cosman was in the hospital after an “accident.” Gitchel reportedly took the son on a long drive, then tried to strangle him.

Martinez-Cosman's car eventually was found on fire. Firefighters believe it's an arson.

Gitchel reportedly told police that Martinez-Cosman left the baseball game with another man. But surveillance video obtained by police from T-Mobile Park shows they left together after the Guardians beat the Mariners 9-4.

Gitchel and Martinez-Cosman reportedly met 12 days before the game at a Costco store. The charges against Gitchel say he went back to that store last Tuesday and stole $10,000 worth of jewelry.

Gitchel was arrested at a Costco on April 5. Police noted he had bruises, along with “many cuts and scrapes on his hands.”

The King County Jail had no record April 10 of Gitchel being in custody.
