Officials in Austin, Texas, say three young people are in custody in at least 10 random shootings that left four people hurt in the city over the weekend. Authorities ordered residents of a large part of southern Austin to shelter in place on Sunday while the investigation continued. They lifted the order Sunday afternoon. Police Chief Lisa Davis says the shootings occurred Saturday and Sunday morning, including two outside fire stations. Davis says the suspects apparently were stealing vehicles. Two were described as boys ages 15 and 17. Police say the third was a juvenile, but did not provide an age or any other details.
