Part 3: The Network Trail
Sarah Vance stood rigid on the concrete curb, her fingers curling into tight fists. She glanced down at the flashing red text on the tablet screen, then looked back up at Arthur Pendelton, her chest rising and falling quickly. “The school’s network is notoriously laggy, Mr. Pendelton. Everyone knows that. The system time is obviously wrong. The device probably cached a glitch from days ago and only registered it this morning when Leo turned it on to show Ms. Reynolds his homework.”
From his driver’s seat three cars back, Marcus Avery watched the interaction through his open window. He saw Leo pull the hood of his sweatshirt over his head, his shoulders slumping as he retreated closer to the rear bumper of the white SUV. The boy kept his eyes locked on his shoes, refusing to look at his mother or the principal.
Arthur Pendelton did not look up from the screen. He tapped the physical volume rocker again, navigating to a secondary system diagnostic page. The blue light from the display cast a cold glow over his wire-rimmed glasses. “The internal clock on these devices syncs directly with the national atomic time server via cellular connection, Mrs. Vance. It does not rely on local school Wi-Fi to keep time. But if you have doubts about the timestamp, we can look at the network log.”
“The network log?” Sarah’s voice lost some of its sharp, demanding edge, replaced by a strained, defensive tightness.
“Yes,” Arthur said, pointing to a line of alphanumeric characters on the cracked screen. “Each time the tablet attempts to bypass the school’s security protocols, it records the service provider and the IP address. According to this entry at 7:42 AM, the tablet was connected to a residential Comcast network. The IP address registered belongs to your home router on Elm Street. The device was not even on school property when the internal accelerometer recorded the impact event.”
Marcus observed the surrounding parents. The father who had previously complained about teacher negligence now crossed his arms and turned his back to Sarah’s SUV, looking away. A mother two cars ahead of Marcus leaned out of her passenger window, shaking her head as she watched Sarah’s posture stiffen.
Sarah shifted her weight, her leather handbag slipping slightly off her shoulder. “My son was asleep at 7:42 AM. I know because I woke him up myself at 8:00. If someone was using his device, it wasn’t him. The tablet must have been hacked, or another student remote-accessed it.”
Arthur Pendelton scrolled down to the final system event block. “The diagnostic log shows the device was unlocked using the face-recognition profile assigned specifically to Leo. Furthermore, the log shows that five consecutive in-app purchases for a mobile gaming platform were attempted between 7:38 and 7:41 AM. The final entry before the physical impact recorded a total charge of eighty-four dollars, followed by a system warning of an unauthorized network bypass.”
Leo let out a sharp, audible gasp, his head snapping up to look at the tablet in the principal’s hands. He quickly reached out to grab his mother’s sleeve, but Sarah pushed his hand away, her eyes fixed on the screen.
“And there is one more detail, Mrs. Vance,” Arthur said, turning the tablet so the display faced her directly. “The system log shows that an automated security notification regarding these attempted bypasses was sent to the primary parental contact email on file at 7:45 AM. The log records that the email was opened and acknowledged on a mobile device three minutes later, at 7:48 AM.”
