Los Angeles police are searching for a man they say stabbed a woman and her 2-year-old daughter in their home, killing the little girl and critically wounding her mother.

Officer Liliana Preciado says officers responding to a call late Monday found both victims with multiple stab wounds on the floor of the home near downtown.

The toddler died at a hospital. Her mother remains hospitalized Tuesday in critical condition.

Preciado says the suspect is described as a man in his 20s.

Detectives have not determined a motive.
