More than a year after a mass shooting in Colerain Township, police announced the arrests of three men who have been charged in the July 2017 killing of Autum Garrett and the shooting of eight others, including three children.

Police said Monday that the shooting on Capstan Drive was drug-related and it was planned. Untangling misinformation and following the evidence to the point of arrest has taken 17 months.

Indicted by a Hamilton County grand jury Dec. 11 were:

James Echols, 23. He faces charges including aggravated murder, aggravated burglary, nine counts of felonious assault and eight counts of attempted murder. He was arrested Christmas Day and is being held in Franklin County, Ohio.

Michael Sanon, 21. He also faces charges of aggravated murder, aggravated burglary and multiple counts of felonious assault and attempted murder. He is being held in Franklin County, Ohio.

Roshawn Bishop, 28. He is charged with murder, felonious assault and attempted murder. He has been incarcerated at the Mansfield Correctional Institution since February on charges of drug trafficking and a weapons violation.

Both Echols and Sanon are Columbus residents. Bishop previously lived in Hamilton County.

Last year, Echols was named as a suspect in a homicide in Columbus, which according to Columbus police happened the day after the Colerain mass shooting. In the Columbus incident, a 19-year-old man was fatally shot and a 20-year-old woman was wounded. Echols was arrested in August 2017, according to news reports, but court records indicate he was never formally charged.

Colerain Township Police Chief Mark Denney said the investigation into the July 8, 2017, shooting was complicated. Some of the victims were not cooperative and police spent time to check out claims from some of the victims that were untrue.

On the day of the shooting, people gathered for a supposed gender-reveal party for Cheyanne Willis, who was 21. Willis told the media that she lost her fetus after being shot in the thigh. But a week later, police announced Willis had admitted she had not been pregnant.

"There were a lot of things we initially believed that turned out not to be true. It hindered the investigation, no doubt about that," Denney said. Police eventually determined they were dealing with witnesses who had connections to more than one drug ring.

"From the very beginning of this investigation, we met significant resistance that is uncommon from victims of crime wanting a resolution," Denney said.

Killed in the shooting was 22-year-old Autum Garrett of Andrews, Indiana.

Garrett's husband, Bryan, and two of their children were also shot. Bryan Garrett was struck in the eye. Officials didn't give details on the children's injuries. Police did say there were no indications the Garrett family was connected to the drug activity that sparked the shootings. It was a case of wrong place, wrong time.

An 8-year-old Fairfield boy was also wounded, according to police reports.

The others wounded were Morgan Bradley, 24; Elijah Clemons, 26, who was Willis' boyfriend and lived at the house; and Willis' mother, Lori White, 51. The family's dog was also shot and wounded.

Police were told the party started at 4 p.m. and about 30 people attended. By 10 p.m., most of them were gone and a movie flickered in the dark living room of the home at 9917 Capstan Drive as the remaining kids and adults – about a dozen in all – watched a Spider-Man movie.

A little after 11 p.m., two men armed with handguns entered the house through an unlocked door, according to police reports, and began spraying the living room with bullets.

Police said at least 14 rounds were fired. Garrett, who was Willis' cousin, was killed on the couch where she sat. She and her family had earlier that day attended a wedding.

Police arrived less than five minutes after the shooting began, finding a front yard filled with people screaming for help.

Witnesses told police the shooters did not say anything or demand property during the incident. They said the shooters entered, fired, then ran away.

Investigators found a pistol in the front yard that police determined belonged to the homeowner.

Willis was involved in a publicized incident that happened on Christmas Eve 2015 near the Forest Fair Village mall in Forest Park. Willis was beaten and had her hair cut off. The attacker also wrote on her face. Video of the incident, which stemmed from a car robbery, was posted to social media.

A woman and a man were arrested in that case, but a grand jury ignored the charges and the two were never prosecuted.

Clemons has been convicted of drug crimes, according to court records. Two months before the shooting, he was accused of aiming a gun at a woman who was changing a baby's diaper. A Hamilton County grand jury did not issue an indictment.

Denney said the investigation was conducted by the Colerain Township Police Department in partnership with the Ohio Attorney General's Office, Bureau of Criminal Identification and Investigation. He said the Cincinnati Police Department assisted handling the crime scene following the shooting.

He praised the work of Colerain Township Detective Corey Boyle, Cincinnati Police Detective John Horn, Special Agent Seth Hagaman and criminal analyst Julie Berry from the Bureau of Criminal Identification and Investigation, and Nathan Richardson from the U.S. Marshals Service.
