Cybersecurity Tech Executive Don Pyle, Wife and 4 Grandchildren Killed in Annapolis Mansion Fire

4-alarm fire destroys $9M mansion in Annapolis, Maryland; 6 residents presumed victims.

Anne Arundel County Fire Department firefighters responded about 3:30 a.m. after an activated fire alarm notification from an alarm monitoring company and a neighbor reported that he saw flames at the mansion near Annapolis.

Presumed victim Don Pyle, his wife and four children were believed to have been in the home that was consumed by fire. Don Pyle was named chief operating officer ScienceLogic, based in Reston, Virginia. The company develops software for cloud computing.

At the childrens’ school, Severn School Headmaster Douglas Lagarde wrote in a letter that Don and Sandy Pyle, owners of the 16,000-square-foot estate at 936 Childs Point Road, and their four grandchildren died in the four-alarm blaze. The childrens’ school — Lower School Chesapeake Campus — is scheduled to be closed Tuesday. An open house previously scheduled for Wednesday has also been canceled.

Agents with the Bureau of Alcohol, Tobacco, Firearms and Explosives and local investigators are on the scene investigating. Over 85 firefighters using tanker shuttle operations took several hours to bring the fire under control.

Searches for victims was delayed because of collapse risk from the ruins of the home. The castle-style mansion, which was built in 2005, was believed to be worth about $9 million before the fire.
