I may be misunderstanding this. First, if you've been convicted or arrested, depending on the state, in certain states, your DNA information goes to CODIS or whatever it is, and is available for LE reference, right?
But for the commercial DNA sequencing services, "Why hasn't LE found a DNA match for Bridge Guy yet in the commercial DNA services' data?" may be that they can't even look without a valid search warrant or other court order, right? (See pasted material below.)
In the medical system from which I retired recently, collecting genetic information from patients required very specific informed consent for every use that might be made of it, with the consent process strictly overseen by an independent ethics board operating under federal guidelines.
I don't know how the commercial services work, but from the '23andme" website (the only commercial service I checked), if I understand it, Officer Krupke can't just roll up and ask to take a peek at your data, again, pasted material below. So Tobe can't just compare that crime scene DNA with the commercial service data, he's got a process, isn't this correct?

Guide for Law Enforcement - 23andMe
" Requests for 23andMe User Information
23andMe chooses to use all practical legal and administrative resources to resist requests from law enforcement, and we do not share customer data with any public databases, or with entities that may increase the risk of law enforcement access. In certain circumstances, however, 23andMe may be required by law to comply with a valid court order, subpoena, or search warrant for genetic or personal information.
23andMe requires valid legal process in order to consider producing information about our users. 23andMe will only review inquiries as defined in 18 USC § 2703(c)(2) related to to a valid trial, grand jury or administrative subpoena, warrant, or order. Administrative subpoenas must be served on 23andMe by personal service just like subpoenas in a court setting. 23andMe will consider releasing additional account information or transactional information pertaining to an account only in response to a court order issued pursuant to 18 USC § 2703(d). In addition, 23andMe will only consider inquiries from a government agency with proper jurisdiction.
To date, 23andMe has never received a request to preserve information potentially relevant to legal proceedings pursuant to 18 USC § 2703(f). If we do receive a valid preservation request, we will preserve a temporary snapshot of the relevant records for 90 days, after which we will automatically remove the information from our servers unless we receive a renewed valid preservation request for an additional 90-day period.
If a 23andMe user completes a valid authorization to disclose their Genetic Information to law enforcement, then 23andMe will disclose the information identified in the authorization. 23andMe will not disclose any identifying information about the authorizing user’s genetic relatives or connections that 23andMe holds unless those users also provide express, written consent.
