A police search warrant says blood was found inside a Charlotte insurance agency that belongs to a man charged in the death of a state insurance investigator.

The warrant released Tuesday said 40-year-old Michael Howell of Indian Trail initially allowed Charlotte-Mecklenburg police to search his Dilworth Insurance Agency. But after they discovered blood on the carpet and a computer cord, Howell stopped them and said they'd have to come back with a warrant.

Prosecutors have charged Howell with first-degree murder in the death of 44-year-old Sallie Rohrbach.

Rohrbach was an investigator with the state Department of Insurance. She was reviewing the books at Howell's business when she disappeared two weeks ago. Her body was found last week in a wooded area near Fort Mill, S.C., about 20 miles south of Charlotte.

Howell told police that he last saw Rohrbach leaving the agency at about 4 p.m. on May 14., WRAL.com reported.
