The suspect is described as a black man who is in his 30s, around 5’9” tall and is lean.

He work a dark hat, a baggy sweat suit, black sneakers and dark cloth gloves during the abduction, police said.

The masked man entered the apartment on San Mortiz Circle around 9:30 p.m., police said. He implied he had a gun and ordered a woman, her teenaged son and a toddler into a back room, where he tied up the son, police said.

A few minutes later, police said, a family friend entered the apartment and the suspect cut him with a sharp object. The father then entered the home and was assaulted too.

The suspect ushered everyone to a family car and ordered them to drive to a nearby ATM, where he ordered them to withdraw money, police said. The suspect told the father to climb into the trunk of the vehicle and drove them to a business park off Innovation Avenue, police said.

The suspect let the family go, but left the father in the trunk of the car, police said. The suspect fled. Once the father realized the suspect was gone, he escaped from the trunk, police said.
