POST FALLS - When Chris Larson saw a "white flash" whiz by and felt his house shake, horrifying thoughts came to mind.

A white Ford F-250 truck crashed onto his Prairie Avenue property north of Post Falls on Thursday with his 9-year-old son, Jake, in its path.

"I ran out of the house the same time Jake ran inside to tell me that a vehicle had crashed," Larson said. "Jake didn't see the truck coming because he was behind our 4Runner getting his backpack from school. The truck missed Jake by two feet and our house by 18 inches."

The truck stopped when it struck a boulder on the property, but the engine was still running when Larson rushed out to check on the victim who was driving a vehicle with local plates.

The incident caused only minor damage to Larson's property, but another pickup on Prairie was struck.

"The crash sounded like when a garbage truck slams down a Dumpster," Larson said.

"The good Lord was watching over us," Larson said. "People have said there were guardian angels watching over our property."

The same could be said for the middle-aged driver, who had an apparent heart attack, because Larson is a paramedic for the Northern Lakes Fire District.

Larson said the victim didn't have a pulse, but was revived thanks to Larson's rescue effort.

The male was continuing to recover at the cardiac care unit at Kootenai Health on Monday, Kootenai County Fire and Rescue officials said.

Larson is humble about his role.

"It was a team effort; we all had a part," he said. "The chain has to start, and it started with me. It just shows you the part citizens can play in the survival chain. We all did what we could."

Larson was overcome with emotion when he described the role Jake and his daughter, Hannah, 13, played during the incident. They retrieved a medical "jump kit" in the shop and assisted in calling 911 despite the traumatic experience - without Larson instructing them to do so.

"With those kids seeing what they did and still being able to assist somebody in trouble ... I couldn't ask for better kids," Larson said. "For them to be cool and calm makes a dad proud."

Larson's wife Angie wasn't home at the time.

"I'm very thankful and blessed that my children were spared and I was able to lend a hand," Larson said. "I hope and pray that the man continues to recover."

Ironically, October is National Sudden Cardiac Arrest Awareness Month. Larson said he hopes the incident serves as a reminder of how citizens can play a role in helping cardiac arrest victims survive.

"I was in shock that this happened at my house, but it can happen anytime and anywhere," he said. "It's something citizens should know."
