A criminal complaint posted to Iowa Courts Online Tuesday sheds more light on the events that led to the death of 23-year-old Ezra Oliver Seymour early Saturday morning and the subsequent filing of murder charges against 25-year-old Trequan Merez Cosgrove, who is also accused of being a felon in possession of a firearm. Additionally, 26-year-old Jaimee Alcaraz-Gutierrez has been charged with accessory after the fact.

According to the complaint, Seymour got into a verbal argument with several people, including Cosgrove, at Cosgrove’s Marshalltown residence on North 12th Avenue. Seymour then left the residence on foot and began walking south, and shortly after, Cosgrove was seen driving away from his home in a white Cadillac.

“Within minutes of the defendant leaving his residence, the victim was found with fatal injuries in the roadway just blocks away to the south. The victim was intentionally struck by the defendant,” the complaint reads. “The vehicle the defendant was driving at the time of the incident was located concealed in the garage of his residence with damage consistent to hitting a person.”

Alcaraz-Gutierrez, who is identified as Cosgrove’s girlfriend in a separate complaint, is accused of helping him hide evidence at the residence they shared after the crime was committed.

“The defendant then opened the garage door, cleared space in the garage and waited for the defendant to pull the suspect vehicle into the garage before closing the garage door. The suspect vehicle had obvious damage to it consistent to striking a pedestrian,” the complaint against Alcaraz-Gutierrez reads.

Cosgrove is being held at the Marshall County Jail on a $1 million cash bond, while Alcaraz-Gutierrez has posted a $5,000 cash bond and been released. In addition to the murder charge, Cosgrove also stands accused of being a felon in possession of a firearm after a gun was allegedly found in his bedroom. Preliminary hearings for both individuals have been set for Sept. 11 at 9:30 a.m.
