The state medical examiner’s office has determined that the death of the Obama family’s personal chef last month was an accidental drowning, officials said Tuesday.

Tafari Campbell was found dead in Edgartown Great Pond on July 24 after he went missing the previous day. Mr. Campbell, 45, was paddleboarding on the pond.

On Tuesday, state police confirmed that the state’s medical examiner officially ruled the death an accidental drowning. Police had previously said that Mr. Campbell’s death was not considered suspicious and he had no external trauma or injuries when he was pulled from the pond.

“This mirrors what our investigation determined, and thus comes as no surprise to us,” said state police spokesperson David Procopio.

Mr. Campbell was a sous chef at the White House during the Obama administration and continued to work for the family when they entered private life.

Mr. Campbell, of Dumfries, Va., was found about 100 feet from shore and was first reported missing in the area of Turkeyland Cove, where the Obama family has a summer home.

The office of the chief medical examiner did not immediately respond to a request for comment Wednesday and state police said its investigation was not yet officially closed.

“[T]here are procedural and administrative actions that need to be taken to officially close it out on our end, but the medical examiner’s determination underscores the facts and circumstances that our investigation found,” Mr. Procopio said.

Mr. Campbell is survived by his wife Sherise and his twin sons, Xavier and Savin.
