GETTYSBURG, Pa.—A jury in central Pennsylvania that could impose the death penalty on a man who killed a state game warden will continue hearing testimony in the case.

The sentencing phase of the trial for 29-year-old Christopher Johnson is scheduled to continue Thursday morning in Gettysburg. He could be executed or spend life in prison without parole.

Johnson was convicted earlier this week of fatally shooting wildlife conservation officer David Grove during a poaching investigation.

Jurors have already heard from Grove's parents and fiancee, who described how much they miss him.

Several friends and relatives of Johnson have also testified. They say he suffered from depression but has been a good father to his 8-year-old daughter.
