CLEVELAND (WJW) — The FOX 8 I-TEAM confirmed Thursday that Cleveland police has asked agents with the state Bureau of Criminal Investigation to look at three unsolved murder cases including two that have made headlines for years.

Cleveland Police Chief Calvin Williams sent a written letter to BCI officials Thursday asking for their assistance with the three cases, including the murder of Aliza Sherman and the murder of Stephen Halton.

Sherman was stabbed 11 times in broad daylight on March 24, 2013. She had gone to see an attorney in downtown Cleveland for a domestic case; the incident occurred just a few steps from the attorney’s office. Police believe the suspect, who still remains free, was caught on video running from the scene. No arrests have been made in the case.

Halton was shot just before 5 a.m. on Jan. 11, 2014 at a bus stop near Grovewood Avenue and Lakeshore Boulevard in Cleveland. The 30-year-old anesthesia tech was headed to work at the Cleveland Clinic to take part in a liver transplant. Portions of streets near the intersection have been named in his honor.

The third case deals with the murder of Ryan Dixon that happened  January 11,  2016.

Dixon, 22, of Middleburg Heights,  was shot multiple times while sitting in a vehicle on the East Side of Cleveland. The shooting happened on Griswold Avenue near East 61st Street.

This comes a month after the I-TEAM broke a story saying the Cuyahoga County Prosecutor was asking for Cleveland to turn the case over to the BCI.

Sheila Halton, the mother of Stephen Halton, told the I-TEAM the family got a call this afternoon from authorities with the new developments.

Sheila Halton said, “I’m excited. Totally excited. I was just crying about Stephen last night.”

“BCI’s Cold Case Unit applies fresh detective work and modern forensic techniques to unsolved cases in partnership with the requesting agency,”  said Ohio Attorney General Dave Yost. “We look forward to working with Cleveland Police on these cases to secure a measure of justice for the victims’ families.”

Last month, Cuyahoga County Prosecutor Michael O’Malley told the I-TEAM his office “fully [supports] BCI taking over as the lead investigative agency.”

Sherman’s daughter Jennifer and other family members also said in March that they wanted BCI agents to take over the case.
