DES MOINES, Iowa — A jury determined Robert Miller III is guilty of killing 4-year-old Marcos Faguada and seriously injuring Faguada’s aunt in a crash on Fleur Drive this past December.

Miller was convicted of vehicular homicide by street racing, reckless driving, and operating while intoxicated. He faces up to 25 years in prison for the operating while intoxicated charge alone and will be sentenced on July 14.

The jury came to a decision at about 12:30 Thursday afternoon after a week of testimony. They spent about five hours deliberating before reaching a verdict on the charges.

“It’s extremely tragic,” said juror Sicely Cooney after the trial. “I was bawling, it was so hard to see this little boy’s body, and the people at the beginning of the accident talking to him. It made me cry and I had to ask for a break, it was so hard.”

On December 13, Miller left the Wicked Rabbit bar on Army Post Road and started speeding on Fleur Drive at more than 100 miles per hour.

“I was still very open minded until we actually watched the video footage in the bar as far as him being intoxicated,” Cooney said. “Seeing the numbers that he blew [a blood alcohol content level of .066] five hours after he got the blood test, it was pretty obvious.”

Miller lost control of his car and went across the median near Grays Lake Park. He crashed into Mayra De Catalan’s car, which was traveling the other way on Fleur Drive. Marcos Faguada, De Catalan’s nephew, was in the back seat and died in the hospital. De Catalan suffered serious leg injuries; she used crutches and a cane in the courtroom during the trial.

“I will probably get some counseling done because of how damaging the pictures were for me,” Cooney said.

Keith Jones, the other driver accused of racing before the crash, will go on trial June 26.
