Kansas City, Kan. ? It’s been more than two months since the woman’s remains turned up in a 55-gallon barrel, and years since she was killed. But Wyandotte County authorities have not given up trying to identify her — and possibly her killer.

“I just want to know who she is and find out who killed her,” said Alan Hancock, Wyandotte County coroner.

The nearly full set of human skeletal remains was found in May by crews who stumbled upon the barrel while working in a wooded area in Kansas City, Kan. There wasn’t much more in the barrel other than the bones, a dark wig tied into a pony tail with lime-green nylon underwear, fake fingernails, jewelry and some trash.

Officials have determined that the woman was from 33 to 56 years old, about 5 feet 6, and of white and Asian ancestry.

It’s unclear when she was killed, but Hancock said Tuesday that based on some of the trash in the barrel — a candy wrapper with a bar code and contest that launched in 1995 — he estimates she was killed after September 1995 and before 2006. Officials have not released the cause of death as it could prove helpful in a homicide investigation.

Because the remains were found in a barrel, there was some speculation that she might have been a victim of Kansas City serial killer John Robinson, some of whose victims’ bodies were found inside barrels. Robinson was convicted in neighboring Johnson County, Kan., of murdering three women from 1985 through 2000, and is on death row.

But Hancock said investigators don’t believe Robinson killed the woman because of how she was killed and other factors, including the location of where she was found, which was miles from where any of Robinson’s victims were located.

“I’m pretty sure it’s not him,” he said. “It’s unlikely.”

Police were also hoping when they released a photograph in June of the jewelry — three rings and a necklace — someone would call with information. But of the dozen or so calls, none has helped.

Kansas City, Kan., Det. Randy Slater said officers have winnowed about 3,000 possible matches of missing women from around the country down to about 600. Calls from people who may have known the victim would help narrow it further.

“I just would have thought somebody would have come up before now,” he said.

To identify the woman by her teeth or DNA would require dental charts or a genetic match to a family member, Hancock said.

“This is just one that ought to be identified. It’s in town, in a barrel. It’s intact,” Hancock said.
