PHOENIX – Mesa police are asking the FBI to help solve two killings linked by forensic evidence.
Saturday, Mesa police announced a link between the Oct. 24 murder of Karen Jane Campbell, 44, and the Nov. 1, 2004, murder of Alisa Marie Beck, 21.
Both women had worked as prostitutes, used drugs and were known to associate with drug dealers, police said.
It is unclear what role the FBI would play, said Mesa police spokesman Detective Chris Arvayo.
Mesa police are contacting other metro Phoenix law-enforcement agencies to check for other murders related to the cases.
Mesa police officers have been advised to make local prostitutes aware of the linked slayings for their safety, Arvayo said.
In three years, not much has changed since police began investigating Beck's death, police said.

Beck was strangled, and evidence indicated she was likely killed someplace else and her body dumped in Mesa, police said.
Beck had no known job or address, and had been in the Phoenix area for a little more than a year.
She reportedly had no ties to Mesa.
During their investigation, detectives learned Beck was a fugitive from Pennsylvania with prior arrests for reckless endangerment, forgery and theft, Mesa police said.
Anyone with information can contact the Mesa Police Department at 480-644-2211 or Silent Witness at 480-WITNESS.
