Police have launched a suspicious death investigation after a male body was found floating in the San Francisco Bay this weekend.

A spokesperson with the Alameda County Sheriff’s office says that the call regarding the body came in at around 8:44 a.m. Saturday morning, with the caller saying that "something was floating in the water," Bay City News reports.

By 10:50, rescue crews had retrieved the body as it floated off the coast of Alameda.

NBC Bay Area spoke with the 911 caller, who says they first noted the remains at around 8:30, "when she spotted something strange in a nearby lagoon."

"I don't see if it's a joke or [if] it's real," Marcela Galvez told NBC, saying that she had been "enjoying her morning coffee on her patio" before the alarming incident occurred.

"I called my wife and she [told me to] call the police."

The death is “absolutely suspicious,” Alameda Police Police Lieutenant Matt McMullen told BCN, which reports that "officers will be investigating it as suspicious until the coroner determines the cause."

Area resident Katie Winton-Henry, who NBC reports "recorded the recovery effort," dismisses this characterization, however, telling the station that she "doesn't believe foul play was a factor."

"There wasn't any wounds, or blood or anything that I could see," she says.

"It's just really sad," she told NBC. "This stuff doesn't happen here in Alameda... It's just really odd to find a dead body and, as a community, I think we just really want to know more."

According to the Alameda firefighters who pulled the remains from the waters, the body is of a "young man." As of publication time, he had not been publicly identified, nor had an autopsy to determine cause of death been completed.
