An alleged attacker and thief struck twice this month in the Bayview, and each time he punched or kicked his female victims before stealing their belongings.

A slate of recent of Bayview nighttime robberies has been targeting women walking by themselves, and police say they have a suspect in custody. The San Francisco Chronicle reports that police announced they arrested Donnell Guidry on May 15, charging him with eight robberies over the last five months. A Bay City News report in the Examiner adds that Guidry is in custody without bail.

Guidry’s alleged attacks go back to January, each involves punching or kicking the women, and in several cases knocking them unconscious. Police say he punched the first victim on January 15 at Third Street and Paul Avenue, stealing her stuff while she was knocked out. In mid-March, he allegedly punched a 52-year-old woman several times, kicked her while she was down, and made off with some of her property. Five days later, police say he struck again at Third and Paul, and all the victim remembered was being knocked unconscious.

He’s accused of attacking and robbing three more women in the Bayview in April, in one case biting the victim’s hand in a scuffle over her car keys. Police accuse him of two more separate attacks the night of May 3, both times knocking the women out and stealing some of their things.

San Francisco police seem confident the same suspect is responsible for each of these attacks. “This happened from January through May, and the suspect was out here terrorizing citizens and stealing their property,” police spokesperson Joseph Tomlinson told the Chronicle. “The good work from the SFPD robbery detail through their investigation were able to determine that this guy was the suspect involved in each incident.”

Police also note they have evidence there could be another victim of this suspect who never reported their attack. Per the Chronicle, they say they found a presumably stolen keychain with a picture of Korean currency. Anyone with information on this is encouraged to call the Police Department tip line at 415-575-4444.
