MAYVILLE — Remains found last week in the town of Portland have been confirmed to be that of a missing Buffalo woman, 50-year-old Marquita Mull, Chautauqua County Sheriff James Quattrone said Thursday. The first set of remains have yet to be identified, though Quattrone said during a press conference in Mayville that they are not of Lori Ceci Bova or Corrie Anderson, both reported missing from Chautauqua County, following an analysis.

Mull was reported missing July 18; she was last seen alive in June. Quattrone said the Sheriff’s Office has been working with police in Buffalo and noted that due to the manner of disposal, foul play is suspected in Mull’s death.

Two sets of human remains were found along the Chautauqua Rails to Trails system — one on Sept. 26 by a woman who had been looking for keys she had lost previously near the trail. The following day, another set of remains were found.

The county has been working with Mercyhurst University’s applied forensic sciences department.

Investigators had been reviewing open missing person cases involving women, including Patricia Laemmerhirt, who was last seen in April 1976; Lori Ceci Bova, who was last seen in June 1997; and Corrie Anderson, who was last seen in October 2008.

Laemmerhirt resided with her husband and children on North Portage Street in Westfield — about 6 miles from Woleben Road in Portland. The New York State Police is the lead agency in the Laemmerhirt case.

According to the National Missing and Unidentified Persons System (NamUs), Laemmerhirt was last seen at the age of 28 on April 3, 1976; she was reported missing by her husband.

Investigators are still working to see if the first set of remains found are that of Laemmerhirt. Quattrone said it could take between four to six weeks at the earliest.

Bova, meanwhile, was last seen in public the night of June 7, 1997, when she, her husband, her sister and her brother-in-law went to dinner at Red Lobster on Fairmount Avenue in Lakewood.

Anderson was last seen Oct. 28, 2008, leaving the former Lake County Dodge car dealership on Washington Street in Jamestown after visiting her boyfriend.
