YOUNGSTOWN, Ohio (WKBN) — Calvin Martin spoke to his girlfriend about 9 p.m. Nov. 3, 2018, while she was at work.

Everything seemed fine.

Three hours later, he was dead on the floor of the living room of his home in the 800 block of Parkview Avenue. He had been shot several times. His then 2-year-old child was sound asleep on Martin’s legs.

Detective Sgt. Anthony Vitullo is revisiting the case. He said there are some leads and “persons of interest,” but police still need more information.

“We have some information but not enough to get us over the hump,” Vitullo said.

In fact, at times there may have been too much information during the investigation, Vitullo said. Vitullo said that can be a hindrance because it makes it harder for investigators to focus on one specific theory or person, and it takes a lot of time to either prove or disprove other theories of the crime.

However, Vitullo said he is confident that investigators have the case narrowed down to the persons of interest he said now remain. He did not want to comment on a possible motive.

Several interviews have been conducted, and shell casings collected at the crime scene have also been sent to the state Bureau of Criminal Identification and Investigation, Vitullo said.

Vitullo said he believes Martin knows whoever killed him. He said witnesses told him that a dog that was in the house would not have been comfortable with someone it did not know being there, and the dog appeared to be calm on the night that Martin was killed.

It was Martin’s girlfriend who found him after she returned home from work, Vitullo said.

Martin’s case is one of nine unsolved homicides from 2018. The others are:

• March 10: Darmetrus North, 38, is shot and killed about 9:45 p.m. at a 2119 Summer Street home.
