Baeza says the officer is at a local hospital in stable condition. The city fire department told the Laredo Morning Times that the 33-year-old officer was shot in the leg, a 21-year-old man was shot in the abdomen and the other person shot was a 53-year-old woman.
A police spokesman could not immediately provide further details on the shooting or the health of those involved.
