Police are looking for a 22-year-old man who allegedly threatened to kill the 18-year-old mother of his son in Mililani.

The woman reported the incident to police about 9:30 a.m. yesterday, saying the man had threatened to kill her unless she met him with their son, police said.

When the woman arrived, the man again threatened to kill the woman and took her to Mililani, where he threatened her with a knife, police said.

The woman escaped and called police, and the man fled before officers arrived. Police have opened a case of three counts of terroristic threatening and kidnapping.
