OAKLAND -- Messages of love and remembrance were posted at a sidewalk memorial on Monday where 15-year-old Denzell Jones and 35-year-old Kanem Ayers were fatally shot Saturday night as they stood outside a Boys and Girls Club in West Oakland.

Police released the victims' names on Monday and said no arrests have been made in the killings, which happened about 10:45 p.m. Saturday outside the club in the 900 block of 24th Street at Market Street.

The memorial, on the Market Street side of the clubhouse, included pictures, posters for writing condolences, candles and apples. The messages were written on the posters dedicated to Denzell, a sophomore at McClymonds High School who was known as "Bean," and Ayers, known as "KK." Notes were left by relatives, friends and people who did not really know them but were saddened by what happened.

Small groups of mourners stood talking to each other, occasionally exchanging waves with people driving by.

Both Denzell and Ayers lived in the area and knew each other.

Police said the pair were standing on the sidewalk when someone approached them on foot and began shooting. Both died at the scene.

Police still have not established a motive.

Oakland schools spokesman Troy Flint said grief counselors were made available at McClymonds for students and others who knew the teenager.

Denzell had picked up an application on Thursday to join the branch that the shooting happened outside of but had not returned it yet, said Calvester Stanley, President and Chief Professional Officer of the Boys and Girls Clubs of Oakland.

Stanley said the community is "losing far too many young people" and his organization wants to do all it can to "help heal and change the (violent) culture that seems to be prevailing. We're just hoping we can do something. Life is too valuable and worth living."

The deaths were the 10th and 11th homicides so far this year in Oakland.

Police and Crime Stoppers of Oakland are offering up to $20,000 in reward money for information leading to the arrest of the killer. Anyone with information may call police at 510-2383821 or Crime Stoppers at 510-777-8572.
