North Dakota ? A jury in North Dakota’s first death penalty case in nearly a century decided Friday that a convicted sex offender should be executed for kidnapping and killing a college student after she left a shopping mall.

Alfonso Rodriguez Jr., 53, of Crookston, Minn., looked straight ahead and showed no emotion as the sentence was announced in the slaying of Dru Sjodin.

The federal jury reached its decision after more than a day and a half of deliberations. The same jury convicted Rodriguez on Aug. 30 of kidnapping resulting in Sjodin’s death.

North Dakota’s last execution was in 1905, and the last person sentenced to death was spared in 1915. The state no longer has the death penalty, but it is allowed in federal cases. Rodriguez was charged under federal law because Sjodin was taken across state lines.
