CLEVELAND, Ohio-- One of the victims of the Orlando nightclub shooting lived in Cleveland with his family for several years.
Luis Omar Ocasio-Capo, known to his family as Omar Capo, he was dancing with friends, including someone he knew from his days in Cleveland, when the gunman opened fire.
Omar Capo's sister told FOX 8 that she received a call from her mother on Sunday morning, indicating that Omar had gone to the club Saturday night, but was missing. They later confirmed that he had passed away.
"I am so heartbroken in so many different ways; I feel like they ripped the most valuable thing I had and it's so heartbreaking for me and my family," said Belinnette Ocasio-Capo, sister.
Omar Capo and his family moved to Cleveland in 2003 from Puerto Rico; in 2012, his mother decided to move the family to Florida.
Tamandra Diaz, a friend of Omar Capo, said the 20-year-old was well known in the Hispanic community for dance-theater.
He is one of the youngest victims in the worst mass shooting in U.S. history.
Earlier officials had said the dead numbered 50 but clarified that they were including the gunman. Around midday Monday, Florida Attorney General Pam Bondi said the families of at least 36 out of 49 victims have been notified of their loved ones' deaths.
The city of Orlando is posting names of the deceased on a website after family members have been notified.
Survivors told horrific stories of the shooting, which began around 2 a.m. Sunday. One person hiding in the bathroom covered herself with bodies for protection. Some entertainers hid in a dressing room when the shooting started and escaped the building by crawling out when police removed the air conditioning unit.
Omar Mateen, 29, was identified this weekend as the person responsible for the massacre.
He initially engaged in a shootout with an officer and then retreated back into the club.
Police tried for hours to negotiate with Mateen, Orlando police Chief John Mina said.
"He was cool and calm when he was making those phone calls to us," Mina said. "We had a team of crisis negotiators that did talk to the suspect just trying to get as much information as possible. ... He really wasn't asking for a whole lot. We were doing most of the asking."
People trapped inside the club desperately called and messaged friends and relatives. Some clubgoers said they thought they were going to die.
At around 5 a.m., police used an armored vehicle to punch through a wall and began pulling people to safety. The gunman came out of that hole, too, and exchanged fire with police, who shot him dead, Mina said.
One bartender recalled crouching, horrified, under the bar.
When police stormed in, they shouted, "If you are alive, raise your hand!"
She did, and was rescued along with others.
At least 53 people suffered wounds in the attack, officials said.
