text: Two Delaware boys are in a coma and their father remains unable to move or talk two weeks after the family became sick from possible pesticide exposure during a vacation on the US Virgin Islands, officials say. Steve Esmond and his wife, Dr Theresa Devine, and their two teenage sons fell seriously ill during their stay at the Sirenusa Condominium Resort on the  island of St. John. The family were airlifted to separate hospitals in Philadelphia suffering major respiratory trauma. Sean, 16, and Ryan, 14, were  in critical condition. Steve Esmond and his wife, Dr Theresa Devine, and their two teenage sons fell seriously ill during their stay at the Sirenusa Condominium Resort on the island of St. John . James Maron, the family's lawyer, said the boys were in 'rough shape'. 'The family are all fighters,' he told WPBF News. 'They're fighting for everything right now. I understand it's a long recovery.' Maron said Esmond, who is an administrator of the private Tatnall School in Wilmington, is conscious but unable to move. Devine, a dentist, was treated and released from the hospital and is currently in occupational therapy. The Tatnall school, where Sean was a star lacrosse player, posted on their Facebook page that they had the Middle School students write get wall cards for Esmond and his family. 'The entire Tatnall community continues to direct its supportive energy toward the Esmonds and asks that everyone keep the family in their thoughts and prayers during this difficult time.' Tuition at the Tatnall school can range from $20,000 to $25,000 a year. Sean, 16, (pictured) and his 14-year-old brother Ryan remain in comas two weeks after being hospitalized . On Friday a spokesman from the US Environmental Protection agency said that the family may have fallen ill because of the presence of a pesticide at the rented villa. Elias Rodriguez said preliminary tests showed there was 'a presence of methyl bromide in the unit where the family was staying'. Methyl Bromide, which is odorless, can be fatal or cause serious damage to the central nervous system and respiratory system, according to the EPA. It is acutely toxic, and only permitted to be used outdoors by certified professionals in the US. Rodriguez said the investigation is 'ongoing' and the agency is still on the island for testing. The family was staying at the $875-a-night  Sirenusa Condominium Resort on St. John in the US Virgin Islands . 'We have been doing different types of air sampling and wipe sampling,' he said. Sea Glass Vacations, which acts as a rental agent for several units at Sirenusa Condominium Resort, said the unit where the family was staying was not treated with a pesticide, but rather the unit immediately below their suite. Maron said when paramedics arrived at the villa Esmond was found unconscious. His sons and wife were having seizures. The US Department of Justice has initiated a criminal investigation into the matter . On Friday  the US Environmental Protection agency said preliminary tests showed there was 'a presence of methyl bromide in the unit where the family was staying'
