    San Francisco police are investigating a death in Golden Gate Park Tuesday morning, a police spokesman said.

    Six people are now in custody in connection with a San Francisco homicide earlier this year in which a homeless man was allegedly beaten and tortured and then thrown into a Golden Gate Park lake, police and prosecutors said Wednesday.

    Two people, Michael Grasso, 26, and Sahmanntha Rundstrom, 19, were arrested Tuesday in connection with the death of 66-year-old Stephen Williams, whose body was found lying face down in Golden Gate Park's Alvord Lake by a gardener on May 24 around 7 a.m.

    Grasso was taken into custody in San Francisco, while Rundstrom was arrested the same day in Flagstaff, Arizona, by police there, Officer Giselle Talkoff said.

    Rundstrom's arrest came about after an investigator with the San Francisco District Attorney's Office who was working with homicide detectives contacted Flagstaff police, Talkoff said. Rundstrom will be extradited back to San Francisco.

    Grasso is being held in San Francisco County Jail on suspicion of murder and inflicting injury on an elder likely to cause great bodily injury, with bail set at more than $1 million, according to jail records. He is likely to be arraigned Thursday, according to the DA's office.

    Four people have already been charged in connection with Williams' death. Police have said he was beaten and tortured over a period of three days before being dragged into the lake.

    Stephen Billingsley, 20, and Nikki Williams, 34, were arrested in connection with the attack and arraigned in June.

    Billingsley, who goes by the alias "Pizza Steve," has been charged with murder, as well as assault, false imprisonment, elder abuse, torture, kidnapping and conspiracy.

    Nikki Williams, who goes by the alias "Evil," is not charged with murder but faces charges including assault, elder abuse, false imprisonment, conspiracy, torture and kidnapping.

    Both have pleaded not guilty to all charges and remain in custody with bail set at $1 million. They are due back in court on September 28.

    Two other people, Robert Tannehill, 35, and Ian Severa, 23, were also arrested in June and named on the same complaint as Billingsley and Nikki Williams, prosecutors said Wednesday.

    Tannehill was ordered to stand trial Tuesday following his preliminary hearing on charges including conspiracy, kidnapping, assault, elder abuse and false imprisonment, and will return to court on Sept. 7.

    Severa remains on the same complaint as Billingsley and Nikki Williams and faces charges of murder, conspiracy, torture, elder abuse, assault and kidnapping.

    Both Tannehill and Severa remain in custody, with bail set at $500,000 for Tannehill and $1 million for Severa, according to jail records.
