DAYTON, Ohio -- Police in Dayton said their latest homicide investigation began with a woman flagging down an officer along North Main Street just after 3 a.m. to tell him about something suspicious she'd just seen. The woman told the officer she'd just driven through an alley a couple blocks away, behind East Norman Avenue and spotted a man laying on the ground and not moving.

Police officers headed that way along with Dayton Fire department paramedics. They discovered a man on the ground in the middle of the alley. Officers took a closer look and realized the man had been shot to death.

Police called in Homicide Squad detectives to take over the investigation. Evidence technicians and Coroner's office investigators also converged on the alley. They discovered the victim is a 39-year-old man who'd actually been shot two times, once in the head and once in the chest.

Detectives said they have only a very little information and would like a lot more as they search for clues about what led up to the man's shooting death. They said the woman who first tipped them off drove away in a purple Dodge Neon without adding anything else. Now police would like to speak to her again and figure out if she saw anything else that could help them. Police said they haven't tracked down anyone else in the neighborhood that heard or saw anything in the area where they discovered the victim.

Officers said they did receive other calls reporting possible gunfire in the general area around midnight and up to 1 a.m.. However, officers did not get exact addresses in any of those calls and could not locate any victims or evidence of a shooting.

Police supervisors said the number of calls in the Norman Avenue neighborhood that runs between North Main Street and Riverside Drive has actually fallen lately. Dayton Police Sgt. Clarence West said there's an easy explanation for that, "Oh, we've been working hard, making busts, both street buys and shutting down houses that we suspect of drug dealing, working pretty hard in this area and a lot of the drug dealing has moved into the street sales and alley sales".

Police said it's way too early in the investigation to know if this shoooting is drug-related although they said that's always a possibility.

On Monday afternoon, police identified the victim as 39-year-old Robert Lee Hines of Trotwood. Officers said he was shot in the head.

Investigators are asking anyone that might have more information about this shooting to call Dayton police at 333-COPS.
