T-R PHOTO BY LANA BRADSTREAM Marshalltown Police Department Capt. Sadie Weekley reviews some evidence handed to her by Marshall County Attorney Jordan Gaffney during the Trequan Cosgrove first-degree murder trial on Wednesday. Cosgrove is accused of hitting and killing Ezra Seymour with a car in August 2024.

During the second day of the first-degree murder bench trial of Trequan Cosgrove on Wednesday, some relevant internet searches were revealed.

Cosgrove, 26, of Marshalltown, is accused of killing 23-year-old Ezra Seymour on Aug. 31, 2024. According to the MPD criminal complaint, Seymour had an argument with several people including Cosgrove at Cosgrove’s home. After Seymour left the residence, Cosgrove drove off in a white Cadillac. Within minutes, Seymour was found on the road with fatal injuries. The Cadillac endured damage consistent with striking a person.

Marshalltown Police Department (MPD) Capt. Sadie Weekley, who testified Wednesday afternoon, told Marshall County Attorney Jordan Gaffney about internet searches pertaining to a Marshalltown vehicular homicide case, which were found on an iPhone belonging to Cosgrove’s girlfriend, Jaimee Alcaraz-Gutierrez.

The internet activity took place the night Seymour died. The vehicular homicide case that was searched occurred in 2012 and involved Derick Bear. Then 18 years old, he was driving an ATV when his passenger, Mario Ortega, 14, fell off and died. Bear was then charged with vehicular homicide.

During Cosgrove’s trial, Gaffney played several video clips showing Seymour walking by North 12th Avenue where he was struck and the white Cadillac, which was the vehicle allegedly used. He also showed video of Alcaraz-Gutierrez, 27, opening the garage door at her home, which she shared with Cosgrove, providing a location to hide the Cadillac. She has been charged with accessory after the fact, and her jury trial has been scheduled for March 27.

Cosgrove is also charged with being a felon in possession of a firearm. In 2019, the defendant, who lived in Mount Pleasant at the time, was found guilty of two counts of going armed with intent, two counts of assault causing serious injury and two counts of assault for the 2018 stabbing of Clayton Meeker and Tony Ramirez in Louisa County after originally being charged with two counts of attempted murder.

If Cosgrove is found guilty of the first-degree murder of Seymour, he faces a maximum penalty of life in prison. Being a felon in possession of a firearm is a class D felony, which carries a maximum penalty of five years in prison and a $7,500 fine.
