El Chapo, AKA Joaquín Archivaldo Guzmán Loera, was considered Mexico's most deadly drug lord.
His multi-millionaire drug empire spanned the globe and was protected by a wall of hitmen and the most vicious members of his cartel.
After being abused by his father as a child, Guzman started his narcotics business first by selling marjuana before seeing his wealth and power soar as he moved into harder drugs and higher stakes.
As the head of the Sinaloa Cartel, El Chapo was one of the world's most wanted man and authorities finally arrested him in 1993.
He was jailed for 20 years but just eight years into his sentenced he managed to escape his maximum security jail and once again take up his place as the head of one of the world's biggest crime syndicates.
Listed as one of the most powerful people in the world, Guzman was arrested and sentenced for a second time in 2014.
But again, the bars of a cell could not hold him and he once again escaped in the most aduacious way possible.
El Chapo was smuggled out of a second maximum security jail through a secret tunnel, which ran underneath his cell in 2016.
For 12 months he remained on the loose, even being interviewed by Hollywood star, Sean Penn, but then in 2016 El Chapo was back behind bars for a third time.
He has been jailed at the notorious Super Max prison, ADX Florence, in America, where he has been ordered to spend the rest of his life.
But if the authorities hoped his drug empire, the biggest in the world, would crumble following his conviction - they were very mistaken.
The Sinaloa Cartel is now run by El Chapos' sons Ovidio, Jesus, Joaquín and Iván, who hold as tight a grip on the Mexican drug market as their father ever did.
The trio are known as the Los Chapitos, which means The Minors, and seem to be immune to arrest and capture by the authorities.
In October last year, Ovidio, nicknamed El Raton, or The Mouse, was arrested in a luxury home in Mexico - but he wasn't under lock and key for long.
As he was taken into custody a huge gunfight ensued, with members of his cartel firing shots at the authorities.
The charge is said by Mexican officials to have been led by Ovidio's older brother, Ivan, who is believed to be one of the leading figures in the Sinaloa Cartel.
Mexico's Security Minister Alfonso Durazo said: "He was one of those leading the mobilization of various criminal elements in Culiacan.
"Ivan Archivaldo was not at the home that was taken over by (security) personnel who participated in this operation."
Hundreds of cartel gunmen flocked to Ovidio's aid - launching a huge firefight at the military forces who held him in their custody.
Chaos broke out in Culiacan as soldiers stormed the area, with fierce gun battles raging in the city's streets, killing at least 13 people.
It left political leaders in Mexico with no choice - release Ovidio to "prevent more bloodshed".
But one of the officers involved in Ovidio's arrested was found with 155 gun shot wounds just weeks later.
And even the global coronavirus pandemic has not slaked the brothers thirst for violence.
The Chapitos are said to have imposed a curfew on the town under the cartel's control - and they have been dishing our severe punishments for anyone who breaks the rules.
"This is no game, we’re not playing," a member of the Sinaloa Cartel reportedly said in one of several videos circulating on social media.
"After ten o’clock at night, all the people must be inside their homes due to the coronavirus, otherwise they will be punished, these are orders "from above (from Los Chapitos)," the video said, referring to the brothers.
They are said to send their henchmen out into the city to punish anyone who breaks the curfews with beatings, torture and huge fines.
The cartel members say that only those essential workers returning home after their workday will be allowed on the streets during the curfew.
Despite their role at the head of one of the world's deadliest cartels, El Chapo's son certainly enjoy the spoils of their violence.
The former drug lord is believed to have as many as 24 children, although the official number stands at 15.
But only four of them are thought to be actively involved in the running of his former cartel - and they have their rivals.
At 39, Ivan is El Chapo's eldest son and reportedly the most senior of the brothers within the cartel - and is the one most focused on wrestling power for the family.
He and his younger brother, are no strangers to the risks of being part of such a notorious family as they were both kidnapped in 2016 by a rival cartel while their dad was still running the business from prison.
Ovidio, or El Raton, is currently wanted by both US and Mexican authorities - even though he was arrested and then freed.
He is believed to be one of the key lieutenants of the Sinaloa Cartel.
Jesus is the only one of El Chapo's sons to be on the Drug Enforcement Administration’s most wanted list and, like his brother, is one of the most vital lieutants in the cartel.
And, aside from his role in the massive drug trafficking operation, he is also known for his lavish lifestyle, which he flaunts on social media.
The fourth brother, Joaquín, keeps a very low profile but is strongly suspected of being heavily involved in the cartel.
But it seems there is one thing the brothers are more than happy to pay for - their sister's wedding.
Alejandrina tied the knot in February in a lavish ceremony, complete with armoured luxury cars and cartel hitmen as security.
The 38-year-old and groom Edgar Cazares arrived in armoured SUVs and the cathedral in Culiacan.
Instead of sharing a dance with her dad during a night-time bash, Alejandrina - who wore a white dress and a tiara - went for a spin with her mum, Maria, who was Joaquin "El Chapo" Guzman's first wife.
Photos show a row of luxury armoured cars parked in front of a cathedral, which was sealed off to the public and under heavy security.
Heavily-armed drug cartel hitmen provided security for the event while senior figures were among the guests, according to Mexican media.
It is believed Ovidio Guzman Lopez, one of El Chapo's sons, attended the wedding, which was presided over by a priest who is close to the Guzman family.
