Johnson was allegedly shot by Scott Dunham, 57, when officers responded to a 911 call at about 6:50 p.m. Tuesday to 2600 Senter Road in East San Jose. The caller said Dunham had access to guns and was distraught and intoxicated.
Dunham allegedly fired a rifle from the balcony of his home, killing Johnson. Another officer killed Dunham in an exchange of bullets.
