Unsecured gun leads to tragic shooting of 1-year-old by 4-year-old sibling in Texas

A 4-year-old boy unintentionally shot his 1-year-old brother in the leg after finding an unsecured pistol in their Houston home. The children's father said the 4-year-old was likely unaware that he had found a real gun, which belonged to a relative staying at the home. The 1-year-old underwent surgery and is expected to survive. The Harris County Sheriff's Office is investigating the incident, and gun safety advocates are urging gun owners to properly secure their firearms away from children. Firearms are the leading cause of death among children in the U.S.
