But Wednesday's meeting was not a random run-in. Montalvo and Shine had sought out the man at his usual hangout spot near the Maryland Exchange.
He is one in a list of about 150 registered sex offenders in Glendale who are paid a visit every year from eight Glendale school resource officers checking to make sure they are in compliance with the terms of their registration.
"We want to keep track of our sex registrants and offenders out there as a matter of proactive crime prevention," Glendale Police Lt. Don Meredith said.
Instead of doing all the sweeps at random through the course of the year, the Glendale Police Department has been doing compliance checks on offenders in one yearly sweep since last year, Shine said.
The department's school-resource officers are designated for the task during the summer because they have less of a workload at that time, and also because it gives them a chance to get familiar with who the offenders are and where they live in relation to Glendale schools and parks, Meredith said.
This week is the first in this year's three- to four-week sweep period.
"We as [school-resource officers] like to know who these people are," Shine said. "It's just another way to protect the children in our community."
Before going out on their checks, the officers will look to see if the offenders have any new warrants, Montalvo said.
Then they get in their cars — always two at a time, and always with a book that profiles every offender in the city — and start the checks.
They will visit the last-known addresses of the offenders, sometimes their workplaces, and if they are homeless, their usual hangout spots, Montalvo said.
They will make every attempt to find them and meet with them, he said.
And if they are out of compliance, police will file a report, Shine said.
