Juan Manuel Marquez reacted to the arrest of Julio Cesar Chavez Jr. in the United States and stated that it is very sad what his compatriot is going through after being requested in Mexico by ties to the Sinaloa Cartel.

On Pro Box TV, Dinamita Marquez lamented that Chavez Jr. is linked to organized crime and asserted that this is not a good image for boxing.

“I think what’s happening is sad. At the end of the day, he’s the son of a figure, the best fighter in the history of Mexican boxing in my view, and I think that living through this is not good, it’s not good for the image of boxing and for the Chavez family. You can’t combine sports with that type of thing, and I think in that sense, as they say, whoever does wrong will end up wrong. I think he has to look into that situation and follow up on it because we’ve seen Chavez Jr. have issues of that type beforehand, and I think they’ve harmed him little by little,” he said.

“He resents it because he’s a colleague in terms of boxing, and seeing who he comes from, what family he comes from, I think in that sense it’s It's worrying and you resent it because he's a good person. I try to greet him, to talk with him from time to time. He's a good person. And when those kinds of things come up you feel sad, because you say 'I never imagined he would end up like that,'" she added. A few days ago, Julio César Chávez Jr. did not appear at the hearing in the Superior Court of Los Angeles County to determine his possible release or the formal start of his deportation process to Mexico, and his attorney Michael Goldstein stated that he did not know his whereabouts. Chavez Jr. was detained by the United States Immigration and Customs Enforcement (ICE) on July 2 in Los Angeles for having an irregular immigration status, since his B2 tourist visa expired in 2024. The Mexican submitted an application to obtain permanent residency in the United States after marrying Frida Munoz, U.S. citizen who authorities say is linked to the Sinaloa Cartel because she was in a relationship with the late son of Joaquin 'El Chapo' Guzman. Shortly after, the Department of Homeland Security (DHS) reported that Chavez Jr. had an arrest warrant issued by the Attorney General's Office (FGR) in Mexico since March 2023 for organized crime and arms trafficking. This is why they were processing his deportation. A few weeks ago, Julio Cesar Chavez Jr. lost to Jake Paul by unanimous decision. The boxer had had problems with addiction and with the justice system in Los Angeles for possession of a ghost gun. After entering rehabilitation and having the charges dismissed, Junior returned to the ring with a victory over Uriah Hall in 2024.

Now the son of the Mexican Grand Champion, 38 years old, -who has a professional record of 54 wins (34 by knockout), 7 losses and a draw- again faces problems with the law.
