One of victims in New Mexico murders came from the Four States

An Oklahoma runaway was one of 13 people murdered between 2003 and 2005, and then buried in a mass grave in Albuquerque, according to published reports.

The body of Syllannia Edwards, Lawton, was one of those unearthed in 2009 on W. 118th Street, in the West Mesa area of Albuquerque, N. M. Albuquerque police, FBI agents, and the Joplin Police Department executed search warrants today on residences and businesses connected to Joplin businessman Ron Erwin, owner of Fox Farm, and the former owner of Eccentrix.

Authorities have said that the key to solving the murders may lie with Miss Edwards, since she was the only one of the victims who was not connected to New Mexico, according to an article in the November 13, 2009, Albuquerque Journal:

Edwards on Wednesday became the eighth of the 11 West Mesa murder victims to be identified, and she does not fit the profile of the other women, officials said. She was 15 years old when she was reported missing from Lawton, Okla., in August 2003, officials said. She was black and had no known ties to Albuquerque.
The other women found buried in shallow graves near 118th and Dennis Chavez SW earlier this year were in their 20s and 30s. They were local women who knew one another and whose lives had intersected through substance abuse and prostitution. They were white or Hispanic.

"When you have a case like this with a serial killer, there is sometimes just one oddball piece of the puzzle that doesn't make any sense," said one official who is familiar with the investigation. "But we're hoping (Edwards) will be crucial to solving this case, crucial in breaking it wide open. The other (victims) all kind of blended into the landscape. But (Edwards) may be unique enough to really help the investigation out."
