ANNAPOLIS, Md. (AP) — The defense is presenting its case in the first-degree murder trial of a New Jersey detective who acknowledges shooting a Maryland man after a bout of road rage last year.

The state rested Wednesday after calling more than a dozen witnesses.

Walker is charged in the June 2013 shooting of 36-year-old Joseph Harvey of Landsdowne. Harvey was shot after the two drivers pulled over on an Interstate 97 entrance ramp following some traffic jostling.

Defense lawyers say Walker thought that he, his wife and three children were in danger when he fired his gun.
