Updated 12:02 p.m. with more details from the Sheriff's Office.
Sheriff’s detectives are investigating a dead body that washed ashore on Miramar Beach around 9:30 a.m., according to a Sheriff's spokeswoman.
A tourist at a nearby hotel notified officials that there was a body floating along the surfline in front of Miramar Beach Inn and Landis Shores Oceanfront Inn.
The dead man is believed to be in his mid-30s and there were no obvious signs of death, according to Det. Rebecca Rosenblatt.
Jen Carroll, a Miramar resident, saw the body on the beach at 9:35 a.m. from her car driving her son to preschool.
"I saw something floating, and it looked like it was a body. I couldn't believe what I saw at first. But it really was a man floating lifeless in the water dressed in clothes," she said.
Hector Morales, a bartender at Miramar Beach restaurant, said he saw about five patrol cars near the restaurant around 9:55 a.m.
“They were wrapping the body and putting it in a ranger truck,” he told Patch.
According to Miramar resident Steve Meneely, a friend walking his dogs along the Miramar beachfront saw a man covered in blood sitting by himself down from where the dead body was found. When asked if he needed help, the man reacted very "agitated" and "rude" and told the dog walker that he better move away.
The San Mateo County Sheriff’s Office is working with the Coroner's office to learn his identity and notify his family.
Patch will follow up with details as they become available.
This is the third dead body that has washed ashore on the coast in 12 days.
