Loveland police arrested a former BJJ instructor on Friday, following an investigation into multiple allegations of child se*ual assault involving two children he had a caregiving role over.
Alexander Hawkeye Martinez, 29, who also goes by “X,” worked at the now-closed Infinite Jiu-Jitsu Academy.
According to sources, the police said the investigation began after the two victims came forward and disclosed the abuse.
Martinez knew both victims and held a caregiver role at the time of the assaults.
Authorities said they are concerned additional victims may exist, citing both his position as a caregiver and instructor and the nature of the allegations.
Lieutenant Heather Moore of the Criminal Investigations Division credited the victims for coming forward:
The courage displayed by these young victims cannot be overstated. Their willingness to speak up made this investigation possible.
Martinez was booked into Larimer County Jail on two counts of Se*ual Assault on a Child – Position of Trust (CRS 18-3-405.3(1)(2), F3), one count of Se*ual Assault on a Child – Position of Trust (CRS 18-3-405.3(1)(2)(a), F3), and two counts of Aggravated Se* Offense Sentence Enhancer (CRS 18-1.3-1004(1)(e)(I)).
A judge set bond over the weekend at $200,000 cash only, with pretrial restrictions in place.
