WARREN - As investigators continued working Tuesday to solve the city's third homicide of the year, police also were searching for the victim's missing vehicle.
The body of Dwayne Hickman, 49, was found with multiple stab wounds on Monday at a Williamsburg Street home. Hickman's sister, Kathy Orwig, had called 911 to ask police to check on her brother because she couldn't find or reach him.
She told a dispatcher she had been riding past the house for several days, and the car was gone. Orwig told the dispatcher it had been more than a week since anyone had seen her brother or talked to him.
Warren police Lt. Jeff Cole, who is leading the investigation, said on Tuesday investigators realized Hickman's vehicle was missing after they were called to his home by a relative.
Investigators confirmed that police were dispatched Monday morning to 3403 Williamsburg St. N.W. - which has a "for sale" sign in the front lawn - to check on the welfare of a resident.
As of Tuesday, no one had been charged in what investigators are calling the city's third homicide of the year and possibly second within a week. All three investigations remain open.
On the 911 tape, Hickman's sister told the dispatcher Hickman had suffered from a stroke and had no strength in his right arm and had trouble walking. She said she did not have a key to the house because her brother changed the locks after a court ordered it be sold following the February death of their mother, who owned it. Hickman was living in the house.
Family in Florida were also trying to reach him but could not, Orwig said.
''My brother has been missing for about a week. And he's like disabled, mentally and physically,'' Orwig told the 911 disptacher.
''I've been trying to call him since Thursday. ... When I call there, his cell phone goes directly to voice mail like the battery has died. His home phone has a message that the voice mail is full. And when I drive by there, all the lights in the house are on but the car is missing,'' she told the dispatcher.
Orwig said she last talked to her brother on March 14 and a sister talked to him on March 17. Orwig had tried to call on March 21 but could not reach him, she told the dispatcher.
An autopsy to determine when and how Hickman died was completed late Monday. The coroner's office did not return messages left Tuesday.
The Trumbull County Auditor's Office website lists Shirley L. Ball as the owner of Hickman's house. According to Tribune Chronicle archives, Ball, who had worked as a clerk for the City of Warren Water Department, died last month. Her obituary published in the Tribune Chronicle on Feb. 11 lists four children among her survivors, including a Dwayne Hickman of Warren. Also listed among her surviving children is Cathy Orwig of Niles. According to a police report, Orwig initially contacted police.
The police report also indicates that the incident occurred sometime between March 17 and Monday.
The other two Warren homicides this year were:
Investigators this week said they are making progress on Fletcher's homicide. However, they declined to elaborate except to say that as of Tuesday, no one had been charged in Fletcher's death.
Meanwhile, Orlonzo Murry, 27, whom city police have named as a ''person of interest'' in Blackwell's death, has remained lodged at the Trumbull County Jail since Warren detectives arrested him at the Franklin County Jail in Columbus earlier this month.
Bond for Murry, of 1016 Bennett Ave. N.W., was set at $150,000. He is charged with possession of a firearm in a liquor establishment. Police said he was at the Sunset when Blackwell was fatally shot.
Police have declined to comment on what role, if any, Murry had in Blackwell's death.
