PHILADELPHIA (AP) — Two men charged in the 2015 shooting death of a Philadelphia police officer during a robbery have pleaded guilty in exchange for taking the death penalty off the table.

Family members of Sgt. Robert Wilson III say they were told late Friday about the plea deal for brothers Carlton Hipps and Ramone Williams that offered life plus 50 to 100 years in prison in exchange for pleading guilty and waving any appeals.

Wilson's family has said they want prosecutors to seek the death penalty and several members were expected to testify against the deal Monday. Last year, a city judge approved a former prosecutor's plan to seek capital punishment in the case.

New Philadelphia District Attorney Larry Krasner promised during his campaign not to seek capital punishment in any case.
