Falling tree branches in Portland area kill 2 people, including high school freshman, authorities say

At least two people, including a 14-year-old high school student, were killed Saturday after they were struck by falling tree branches in the area of Portland, Oregon, authorities said.

Kelly was volunteering to plant trees when he was struck by the fallen limb around 11:15 a.m. in Thousand Acres Dog Park at the Sandy River Delta in Troutdale, about 17 miles east of downtown Portland, the sheriff's office said. 

"Our thoughts are with this young man’s family during this tragic time," said Undersheriff Nicole Morrisey O’Donnell. "This weighs heavy on all of us in the first responder community."
