Jurors are hearing their second day of testimony in the trial of a man accused of shooting into a Milwaukee house where five-year-old Laylah Peterson was killed. Twenty-one-year-old Carl Barrett, Junior was one of three people charged in the November 2014 shooting — in which police said they shot at the wrong house after targeting a rival who had just been acquitted for another killing. Police say shell casings at the Peterson house came from the same gun used in two other Milwaukee shootings — and Barrett was a suspect in both. Prosecutors plan to call up to 40 witnesses, and the defense decided to wait until after the state rests to make its opening statement. Barrett is charged with reckless homicide and three counts of reckless endangerment while the other alleged shooter, 24-year-old Arlis Gordon, pleaded guilty last week to reduced charges — and an accused getaway driver has also pleaded guilty to lesser counts.
