DAYTONA BEACH, Fla. -- A Florida Department of Law Enforcement criminal profiler said a serial killer committed three unsolved murders in Daytona Beach since December, police said Friday.

Special Agent Tom Davis believes the suspect is a male who targeted the three female victims because of other stressors in his life, according to a police statement.

No suspects have been identified, the statement said.

"It is believed that a close acquaintance of the perpetrator is the source of causal stress in his life and that this person may become a victim in the future," the statement said.

Laquetta Gunther, Julie Green and Iwana Patton were all killed by gunshot wounds. Gunther's body was found in an alley on Dec. 26. Green's body was discovered Jan. 14 on a dirt road at a construction site, while Patton was found on a dirt road Feb. 24.

No evidence so far indicates any of the women was taken against her will, the statement said.

Police are withholding further details about the murders, victims and Davis' report, citing concerns that it could hinder their ongoing investigation.
