Police are searching for a week-old baby that went missing after its mother was shot dead.

Officers began a hunt for the newborn they described as "missing and endangered" after a relative found the mum dead in an apartment.

The mother was found fatally shot in Wichita, Kansas.

Police want to talk to anyone with a relationship to the victim, while officers also put out an alert saying the driver of a purple Cadillac who was a person of interest in the case had been found and questioned.

He is not considered to be a suspect.

Police also said the child's father is not considered a suspect either.
