SAN FRANCISCO — Five people were arrested Tuesday — including two facing murder charges— for the death of a man found bound and gagged in the middle of a street in San Francisco, police said.

Maelene Lintz, 32, of San Francisco and Montrail Brackens, 21, of Oakland, were arrested at a home in suburban Hercules on suspicion of murder, said Officer Albie Esparza, a police spokesman.

Three other suspects, Tyler Miller, 19, and Heather Leach, 24, both of Hercules and Maryann Manalastas, 22, of Oakland, were also arrested Tuesday and each faces accessory to murder charges.

Lintz and Brackens are being held in jail without bail, San Francisco Sheriff's spokeswoman Susan Fahey said Tuesday. Miller is out on an unspecified bail as Leach and Manalastas are in custody on $15,000 and $20,000 bail apiece, Fahey added.

It is not known if the suspects have attorneys.

The arrests came two days after victims Stephen Reid and a woman were found tied up and gagged on a street in San Francisco's Visitacion Valley neighborhood late Sunday.

Reid, 26, died early Monday at a local hospital from a gunshot wound and blows from a blunt object just hours after he was found. The woman, 18, was hospitalized in critical condition and is expected to survive her injuries. Her name has not been released.

Several unanswered questions remain as police would not disclose a motive as investigators said the incident wasn't random as the victims and the suspects knew each other well.
