John Espinoza, the owner of the house on the 6400 block of 33rd Street, said he left his garage open while he and his family were at home. He says intruders armed with large guns entered his home through the garage and asked for his wallet and his wife's purse. Espinoza refused to surrender the items, he said. Unarmed, he chased the assailants through the backyard to the next street, he said.
