He survived his wounds, which left him blind in one eye and with impaired motor skills. Now 12, he was the only member of the Lillelid family to survive that fateful night 10 years ago.
Peter resides with his maternal aunt's family in Sweden.
Reached by telephone at her home in Sweden this morning, Peter's paternal aunt, Randi Heier, said, "he is doing fine," when asked about Peter.
But she declined to comment further.
When reminded that today is the 10th anniversary of the murders, Mrs. Heier said, "Actually we have not been talking to the media for the last nine years."
She noted that the only exception had been a television interview granted to a Knoxville television station.
"When we decided to say yes to that interview, we decided that that would be the only one," she said.
She noted that the Heier family had received other interview requests from media in Tennessee, Sweden and the Lillelid family's native Norway.
When asked to pass along to Peter the good wishes of Greene Countians, she said, "Thank you very much. I know the people of Greeneville were very helpful 10 years ago."
When a reporter noted that it was difficult to believe that Peter is now 12 years of age, Randi Heier said, "yes, time passes very fast."
