A two-year-old boy in Houston has died after shooting himself in the head with an unsecured gun that he found inside his home, according to Texas police.
The parents of the child - Christopher Williams Jr - were home at the time of the afternoon shooting, police say.
Police believe a 9mm handgun found at the scene is owned by the boy's father. It was unclear if the parents will face charges.
Several US children accidentally shot and killed themselves in recent days.
The Houston Police Department (HPD) say they are trying to determine how the boy - nicknamed "Junior" - accessed the gun before the shooting around 12:50 local time (17:50 GMT) on Sunday.
In a news conference HPD Special Victims Captain David Angelo appealed to gun-owning parents to take precautions.
