(CBS8) San Diego — Two people were killed Monday when a roughly 75-foot-tall tree fell onto a two-story house in the Point Loma Heights area.

The tree fell around 6:15 a.m. at a home near the intersection of Santa Monica Avenue and Santa Barbara Street, San Diego Fire-Rescue Battalion Chief Rick Ballard said.

Two people were pronounced dead at the scene, Ballard said.

A fellow business owner from Grand Forks, North Dakota, identified the victims as Troy and Jessica Nelson – owners of Trojan Promotions. She also said an uninjured person in the home was Jessica’s brother Ryan Langerud.

Police confirmed that the couple was asleep in bed when the tree crashed through the roof without warning. It is suspected they died instantly.

The website VRBO.com has a listing for a home that appears to be the one involved in the tragic tree fall. The listing for the 1,000-square-foot, two-story house has almost 80 reviews on it. A phone call to the person named as the owner went unanswered.

San Diego Gas & Electric crews were called to the scene to repair some downed power lines and shut off gas to the home, Ballard said.
