A team of private investigators converged Monday at the site of a home destroyed in an apparent natural gas explosion.

Last Thursday’s blast at 410 Wellingford Street, near West Sugar Creek Road and North Tryon, killed 4-month-old Synora Coleman and injured her parents.

Two men were seen Monday morning carrying a gas-fired water heater from the pile of furniture, wood and drywall where the home once stood.

A man wearing coveralls with the logo of Raleigh-based Accident Reconstruction Analysis, Inc., declined to say why the private investigators were examining the debris.

A Web site for the company says its employees are hired by major appliance manufacturers, attorneys and other clients to examine accidents.

The Web site says the company and its employees have been involved in several high-profile cases, including the Space Shuttle Challenger explosion and the collapse of the pedestrian bridge at Lowe’s Motor Speedway.

Fire investigators have not said what caused the explosion, but they have said it was fueled by natural gas.

A news conference that had been tentatively scheduled for Monday afternoon was postponed.

Charlotte Fire Department Spokesman Capt. Mark Basnight said authorities believe they have pinpointed a cause for the blast, but investigators still wanted to conduct additional interviews before releasing their preliminary findings.

Basnight could not say if investigators have interviewed the two adults who were in the home at the time of the explosion.

Courtney Chambers was listed in good condition Monday afternoon at Carolinas Medical Center.

Her boyfriend, Syl’Myles Demecio Coleman, 25, remained in critical condition at Wake Forest University Baptist Medical Center.

Coleman’s uncle, Elbert Coleman, said doctors told the family his nephew would likely remain hospitalized for two months.
