CHAPIN, S.C. — Wildlife officials say a boat wreck that killed two people on a South Carolina lake was caused by the boat driven by one of the men killed.

The report on the April 21 crash from the Department of Natural Resources said 37-year-old Danny Phillips should have yielded the right of way to the other boat as it approached the vessel from the left side on Lake Murray.

The report said the driver of the second boat stayed on the scene for several hours and passed a field sobriety test. Authorities say eyewitnesses backed that account. Prosecutors did not file charges.

Wildlife officials say Phillips had a high level of marijuana in his system. He died in the wreck along with a passenger in his boat, 28-year-old Shawn Lanier.
