Thunderstorm causes 2 deaths

The destructive thunderstorm that tore through the region Sunday afternoon resulted in the deaths of two people -- a 6-year-old boy and a woman in her 40s.

One death occurred when the 6-year-old boy was struck by a falling tree limb in Loudoun County about 3:15 p.m. The other occurred when a tree fell on a minivan in College Park about 3:30 p.m., killing a woman.

The Loudoun death occurred as the boy was walking on a trail with his family near the Claude Moore Recreation Center in Sterling, a spokesman for the county sheriff's department said.

The woman who died in her vehicle on Rhode Island Avenue near Odessa Street in College Park was described as in her 40s. Mark Brady, a spokesman for the Prince George's fire and EMS department, said the woman's mother, who was also in the vehicle, was taken to a hospital with serious injuries.
