California authorities are looking for a teen mother and her daughter after they were last seen on October 29.

The Hanford Police Department believe 16-year-old Diana Zamora Cardenas run off with her 1-month-old daughter, Davina Alcala, and the baby’s father who is wanted for homicide.

Police say Cardenas was last seen on Sunday with her daughter and was not being cooperative in the homicide investigation.

The father, 19-year-old Nicolas “Nico” Alcala, is wanted in connection to the Fresno County murder of Pedro Aispuro.

Aispuro, 34, was shot outside a taco truck in Huron, Calif. on June 4 when a fight broke out. Aispuro was shot multiple times, and though he had survived being shot four times in January, he was unable to survive this attack.

Authorities believe the teen mother and Aispuro may be heading to Mexico.

Fliers with photos of Cardenas, her child, and Alcala have been distributed and Alcala is believed to be armed and dangerous. Hanford Police are asking anyone with information to call them at (559) 585-2540 or contact the National Center for Missing and Exploited Children at (800) 843-5678.

Cardenas is described as a Hispanic woman, who stands at 5’1, with black hair and brown eyes. She is 16 and weighs about 118 pounds. Her daughter was born on September 19 and weighs about 8 pounds.
