A 29-year-old facing charges in a fire that damaged an America Street apartment home last month is not thought to be involved in the rash of arson fires in downtown Charleston, police officials said today.

Rhashalm Antonio Crowell of Spruill Avenue in North Charleston faces a charge of third-degree arson.

Officers who responded to reports of a fire at 37A America St. found the stairway and front door on fire, according to a statement from the Charleston Police Department. They used extinguishers to douse the blaze.

The apartment house was occupied, but no one was hurt.

Parts of the downtown near the Crosstown Expressway have seen as many as 85 suspicious fires since 2002, according to aPost and Courier analysis. Many of these fires began in the early morning hours outside apartment houses.

The circumstances of the America Street blaze led investigators to believe it wasn’t connected.

“Crowell had threatened to harm a woman who was living in the apartment,” the statement said. “No information has been obtained to indicate that this incident is related to other fires in the downtown area.”
