Frisco Man Arrested in Collin County on Child Sexual Assault, Alcohol Charges

John Elden Mashtare Jr., 46, was taken into custody by Frisco Police SWAT after officers served arrest and search warrants at his Stone Canyon Drive residence on Feb. 3, court records and an arrest affidavit show. The operation at the five‑bedroom, seven‑bathroom property began with officers loudly announcing their presence and knocking at about 9:10 a.m., the affidavit says.

Court records and jail logs list charges of child sexual assault and purchasing alcohol for a minor against Mashtare. The allegation described in an affidavit summary circulating on social media says a 16‑year‑old girl reported that on Sept. 24, 2025 Mashtare took her to a Frisco bar, bought her alcoholic drinks and later brought her to his home, where she alleges they had sexual intercourse while she was intoxicated. A social post summarizing the affidavit says surveillance footage reportedly shows the teen seated with Mashtare at the bar during the relevant time.

The arrest affidavit obtained in reporting describes the execution of the warrants in detail. According to that affidavit, SWAT members and drone operators observed Mashtare leave the home and move into the backyard, where two officers issued verbal commands to surrender. Mashtare did not immediately comply and moved out of sight behind a pool grotto, and an overhead drone captured him "attempting to place an item" on or near the backyard air conditioning unit, the affidavit language quoted in coverage says.

Photos shared with local media show multiple SWAT officers outside the Stone Canyon Drive residence during the operation; the home is described in public reporting as a multi‑million‑dollar mansion and is estimated at about $2.7 million on Zillow. The property description in coverage lists five bedrooms and seven bathrooms; no house number was published in the reports.

Social media reaction in Collin County followed the arrest notice, with local users reposting the headline and commenting on the SWAT operation and alleged offenses. One Instagram user, mr.c.23.t, wrote, "Ok I need Frisco less in the news please 😂😂" while other commenters invoked neighborhood reputations and broader controversies; those posts are documented as public reaction and not evidence in the investigation.

Reports do not include a full affidavit text, booking number, bond amount or specific court docket information. Mashtare was taken into custody at the conclusion of the warrant service; court filings and jail logs list the charges but do not provide further public details about bond or scheduled hearings in the material reviewed. Frisco Police and court records would be the next sources to confirm docket numbers, any evidence recovered from the property and the dates for formal charges and appearances.
