Mark Allen Blakley III, 28, was found dead in a wooded area in Comstock Park, Michigan, on June 15, 2025. An autopsy later determined he died from multiple gunshot wounds.

Police tied the discovery to a shots-fired call earlier that day in a nearby area. Officers arrested 18-year-old Santiago Barajas at that scene on a concealed-weapons charge. According to court documents, investigators say the encounter grew out of a Facebook Marketplace sale: Barajas arranged to sell a watch to Blakley, and told detectives Blakley grabbed the watch and fled. Prosecutors allege Barajas then drew a concealed handgun and fired twice, striking Blakley in the back and neck.

Barajas was charged with manslaughter and felony firearm, arraigned, and held on $200,000 bond. If convicted of manslaughter, the charging documents say he faces up to 15 years, plus two years on the weapons count. Does anyone have information about the Marketplace transaction or the events leading up to that meeting?
