DENVER -- Denver police are investigating a deadly stabbing that occurred around 2:45 a.m. in front of an apartment building near 18th and Gilpin.

Police say they were answering a 911 call about a fight when they found a Freedom Cab driver lying on pavement with numerous stab wounds. The man was rushed to Denver Health Medical Center where he died.

Amber Torrez, 19, was taken into custody. Police said she was found leaving the scene and had what appeared to be blood on her clothes when police confronted her.

There's no word on what the motive may have been or what the relationship was between the man and the woman.

The stabbing occurred inside the cab in front of the man's apartment. After he was stabbed repeatedly, the man apparently stumbled toward his home, but collapsed on the pavement, where family members found him lying in a pool of blood.

The man's cab was towed away with one of its turn signals still blinking and its engine still on. Neighbors told police that they heard arguing.

The man, who has not been identified, had worked for Freedom Cab for years and was an employee in good standing, the company said.
