MARSHALLTOWN — Ezra Oliver Seymour, 23, of Tama, was pronounced dead on Saturday after he was intentionally run over by a car in Marshalltown early that morning. Trequan Merez Cosgrove, 25, of Marshalltown, who had previously been convicted of multiple felonies in connection with a 2019 stabbing incident in Louisa County, has since been charged with first degree murder for his alleged role in Seymour’s death, and Cosgrove’s girlfriend Jaimee Alcaraz-Gutierrez has been charged with accessory after the fact.

According to a criminal 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.

According to court records, a Louisa County jury found Cosgrove guilty of two counts of going armed with intent and two counts of assault causing serious injury, all Class D felonies, back in 2019 in connection with the stabbing of two men near Wapello. At the time, he was sentenced to serve two consecutive five-year prison terms for the assault convictions as well as concurrent sentences for going armed with intent.

In 2022, Cosgrove was also charged with first degree burglary in Marshall County, but a court only found him guilty of domestic abuse assault — injury or mental illness first offense. He received a suspended sentence and was placed on probation for a period not to exceed a year, and he was officially discharged from his sentence on Oct. 28, 2023, and his probation in November of 2023.

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.
