One person is confirmed dead after a helicopter crashed into a home Sunday afternoon in the College Park area of Orlando.

Police have closed off roads near the intersection of Edgewater Drive and Seville Place.

The helicopter departed from HQ Aviation LLC, which is located at the Orlando Executive Airport. The crash happened around 2:15 p.m. along Alameda Street.

It's unclear how many people were on board the helicopter when it crashed into the guest portion of the house. No one was inside the guest house at the time of the crash, police said.

"We don't know what caused the accident, we just know the helicopter did go inside the guest house," said Sgt. Wanda Ford, of the Orlando Police Department.

Residents inside the other area of the house weren't injured.

Neighbors who live in the area said they were shocked when the helicopter went crashing through the roof.

"I was driving down the road, and I just saw this helicopter and it was driving really low and the propeller was still going, but you could just tell that it was about to crash," said Emily Blomquist, who lives in the area.

Donn Carr added: "I heard this great whop, whop, whop -- followed by this boom. Then everything went dark."

About 33 customers were without power as of 10 p.m., according to Orlando Utilities Commission.

The Federal Aviation Administration and the National Transportation Safety Board are currently at the crash site as the investigation continues.
