James Chisum, 37, was shot and killed at his Modesto home on October 21, 2018 while holding his 18-month-old grandson. The shooting occurred at the residence near Yosemite Boulevard and El Vista Avenue; the child was not injured. Authorities say the shooter, Stephen Patrick Tisdale, believed Chisum was a drop-out from the Norteno criminal street gang, a motive investigators have linked to gang-related violence in the area.

Tisdale was arrested along with four others — Raymond Zavala, Mariah Silva, Pedro Araiza, and Rodrigo Gomez — on charges tied to the attack. Charges reported against Tisdale included murder, attempted murder, participation in a criminal street gang, child endangerment, auto theft, and home invasion; the other suspects faced various charges including murder, gang activity, and home invasion robbery. Prosecutors say Tisdale was connected to other shootings in October 2018.
