According to UCPD Chief Victoria Harrison, canine patrol officer Craig Chew of the OPD shot Denovo three times in self-defense after she lunged at Chew with a machete. Chew had previously been shot five times in July 1991 by a teenage robbery suspect during an investigation in Temescal, and had just returned to duty in July 1992. In addition, Chew had been investigated three times in 1989 for the use of excessive force during his tenure with the Berkeley Police Department, where he served prior to joining the OPD in 1990.
