Logan Bain lived only seven weeks.
He died March 27, 2009, after suffering blunt trauma to the head.
Seventeen months after his death, an Erie County grand jury has indicted his father, Matthew Bain, 27, for murder.
The Erie County Prosecutor's office sent the case to the grand jury, which met Sept. 9 and obtained a secret indictment for Matthew's arrest, charging him with murder, negligent homicide, reckless homicide and endangering children.
"This is a tough case," said Kevin Baxter, Erie County prosecutor. "It takes time to develop. We've got one shot at these cases."
Shortly after Logan was born, he was hospitalized for surgery on his intestinal tract. He was released from the hospital to his parents, Matthew Bain and Dayna Gadberry, on March 3, 2009.
About three weeks later, on March 27, the infant died at Firelands Regional Medical Center.
Days later, the Lucas County coroner's office ruled the death a homicide.
Baxter said the case was difficult to investigate because he wanted to avoid double jeopardy, which prevents someone from being tried on the same charge following a not-guilty verdict from a jury.
Logan's parents were interviewed after the death, but their explanations about the events that night weren't consistent with the Lucas County coroner's autopsy report.
The coroner's ruling came to public attention a few months ago, when the Erie County Health Department posted its annual report online. For nearly a year prior to that, it was unknown that Logan was murdered.
Baxter said police and children services continued their investigation over the past year, meeting periodically with the prosecutor's office and interviewing the parents and others.
All along, they were unable to provide any additional evidence.
"Just simply, time had passed and we felt we needed to move it to a grand jury," Baxter said.
Sandusky police Det. John Orzech said detectives met frequently with childrens services and the prosecutor's office to discuss the case.
Still, Orzech couldn't remember when investigators met last.
Bellevue police, acting on a warrant from Erie County Sheriff's Office, arrested Matthew Bain at his Bellevue apartment on Wednesday. He was booked into the Erie County jail and is being held on $150,000 bond.
No one answered the door at Bain's apartment on Steeplechase Drive. A neighbor, Anthony Smith, said Bain lives there with a girlfriend.
Police officers knocked on the door for a half-hour with no answer, but when they got a key from apartment management, they found Bain and his girlfriend in the living room.
