CUMBERLAND COUNTY, N.C. — Investigators are testing a purse and a wallet to determine whether they are linked to a missing Lee County woman.

Dozens of volunteers focused on a 25-square-mile area in Cumberland County over the weekend in search of Michelle Bullard, 23, who disappeared after a reported home invasion on Jan. 2.

Volunteers found the wallet and Bullard's purse in a ditch over the weekend and turned the items over to the Cumberland County Sheriff's Office.

Investigators think the wallet may have belonged to one of the men in the trailer at the time of the alleged home invasion.

The latest search came after a local criminal profiler, Dr. Maurice Godwin, created the map, which is based on his research of the case. He believes Bullard, if she is not alive, will be found in the area.

Last week, dozens of volunteers and law enforcement agencies assisted in a search in Cumberland County along Bogie Island Road after a man found a wallet with Bullard's ID inside.

The four-week investigation into Bullard's disappearance has spanned across three counties -- Lee, Harnett and Cumberland.

Bullard is 5 feet 2 inches tall and weighs about 125 pounds and has brown hair and brown eyes.

A $10,000 reward is being offered to anyone who has information leading to her recovery.

Anyone with information that may help solve the case is urged to contact the Lee County Sheriff's Office at (919) 775-5531, Cumberland County Sheriff's Office at (910) 323-1500, or their local law enforcement agency.
