Yessenia Suarez, thalia Otto and Michael Otto

Twenty-eight-year-old Yessenia Suarez and her two children: nine-year-old Thalia and eight-year-old Michael Otto were last seen on October 22, 2013 in Deltona, Florida.

Yessenia's relationship with her husband, Luis Toledo was strained. She was having an affair with one of her coworkers at her job. That afternoon, Luis showed up at Yessenia's workplace, argued with her about the affair, slapped her and left before the police arrived. Luis later called his mother-in-law, begging her to convince Yessenia not to press assault charges against him.

After work, Yessenia joined Thalia and Michael at her mother's house where Luis called the house, warning Yessenia that "something would happened" if they tried to get an injunction against him. Although Yessenia left the house to get the injunction, she changed her mind and came home without it, telling her mother that getting it would make things worse.

Luis came over to the house, spoke to Yessenia and her mother about their marriage, and left. Yessenia planned to stay the night there with the kids so Luis could calm down, but she changed her mind at 8:00 that evening and decided to take them home instead.

Yessenia sent texts to Luis throughout the day. They last spoke to each other for five minutes later that evening. When Yessenia failed to call her mother the next morning like she usually did, the mother called the police at 10:00 a.m. and asked them to check on the family's welfare.When the police went to Yessenia and Luis's house, it was empty. One of her cars was left in the driveway of the home and another car was located in the parking lot of a Publix store in Lake Mary, Florida on the same day that Yessenia, Thalia and Michael were reported missing.

On October 24, 2013, police announced that Yessenia, Thalia and Michael were dead. Two days later, Luis was charged with second-degree murder in Yessenia's death and two counts of second-degree murder in Thalia and Michael's deaths.

Neighbors heard screams coming from Yessenia and Luis's house around the time Yessenia and her children went missing. Police discovered Thalia's blood on Luis' boots, the trunk mat from one of Yessenia's cars, in the master bathroom and master bedroom. Some of Michael's blood was found on two pieces of gauze in a trash can in the master bedroom.

Luis reportedly confessed to murdering Yessenia, but claimed that a neighbor was responsible for murdering Thalia and Michael; however, police don't believe that the neighbor had any part in the crime.

In October of 2017, Luis was found guilty on all charges and sentenced to life in prison. Yessenia, Thalia and Michael have not been located, but foul play is suspected in their cases which are classified as being an endangered missing person.
