The trial has begun for a Waterloo man charged in the death of his 17-month-old son in 2011. Prosecutors alleged in opening statements Wednesday that 24 year-old Daniel Reddout killed his son, Kaleb, by choking him in an effort to put him to sleep. Reddout is charged with first-degree murder, child endangerment causing death and child endangerment multiple acts. He's pleaded not guilty and his attorneys declined to outline their case in opening statements. Prosecutors told jurors that Reddout had a technique he used to put his son to sleep that involved lifting his jaw and applying pressure to his back. Prosecutors say he used this method the day the child died.
