Boston Man Guilty of Killing Teenager

A Jamaica Plain man pleaded guilty Wednesday to killing a teenager outside a South End house party nearly two years ago.

Johnnie Bonnie, of Jamaica Plain, pleaded guilty to voluntary manslaughter on the day his trial was set to begin, Suffolk County District attorney Daniel F. Conley announced Wednesday.

Bonnie faces a possible 20-year prison sentence, in addition to the time he is already serving on an unrelated gun conviction in 2015. Judge Jeffrey Locke is scheduled to sentence Bonnie Thursday at 9 a.m. in Suffolk Superior Court.

Bonnie shot 17-year-old Evens Archer in the head outside a party on Castle Court in Boston’s South End on June 28, 2014, the district attorney’s office said. Surveillance cameras captured Bonnie running down East Berkeley, onto Shawmut Avenue, where he crouched by a sewer grate. Investigators later found a gun matching the bullet fired at Archer, Conley’s office said.

Before police had finished their months-long investigation, Boston Police arrested Bonnie on the separate gun charge, for which he is serving 5-7 years.
