MARIN COUNTY (KRON) — A fight involving gunfire and bats left two people dead and another in the hospital on Sunday morning in unincorporated Marin County, authorities said.

The first report was called in at 9:58 a.m. of a fight on Cole Drive in the unincorporated community of Marin City, sheriff’s spokesman Lt. Doug Pittman said.

Most of the altercation took place at 99 Cole Drive but a person initially found to be in critical condition from a gunshot wound ran to 79 Cole Drive. Deputies do not know whether the person ran to escape further injury or to escape being caught by deputies, Pittman said.

The person is still in the hospital but their condition has greatly improved, he said.

The first 911 callers said the altercation involved bats or sticks and other weapons. But when the first deputies arrived dispatchers starting receiving calls saying that shots had been fired.

Sheriff’s officials are not saying whether the two people who died did so because of gunshot wounds, according to Pittman.

The two were found outside an apartment building at 99 Cole Drive.

The Marin County coroner’s office has identified two people killed in Marin City on Sunday as Jacari Lloyd Devon Cook, 29, and 60-year-old Carl Lee Breaux.

Pittman said there seems to have been some type of argument between a man and a woman at 99 Cole Drive.

Pittman said investigators are trying to determine whether the two people who died tried to intervene in the argument.

“That’s what we’re trying to put together now,” he said.

All the people involved in the altercation knew each other, Pittman said.

That’s why investigators believe there is no further threat to the community, he said.

This is the second homicide in Marin City in nine months and the suspect in the previous homicide is still at large.

But investigators don’t believe there is any connection between the two killings, Pittman said.

Deputies are asking anyone who has information about the altercation to come forward to help deputies put together the puzzle surrounding the arguments and deaths.

Sheriff’s officials are not releasing the names of the suspects until they have identified all the people who are key to the investigation, Pittman said.

The names of the two who died may be released this afternoon after the coroner has identified them and their families have been notified.

“Horrific,” Pittman said of the deaths.Bay City News Service contributed to this article
