Court documents show Fotis Dulos' friend's cellphone was seized at Newark Airport during a federal investigation by the  Department of Homeland Security connected to the disappearance of New Canaan mom, Jennifer Dulos.

Jennifer went missing in 2019 when she was last seen bringing her children to school. 

Her estranged husband Fotis Dulos and his girlfriend Michelle Troconis were almost immediately named as suspects in Jenniefer's disappearance, and Fotis was eventually charged with her murder. 

Troconis was charged with conspiracy to commit murder, evidence tampering and hindering prosecution.

Fotis killed himself in 2020, just weeks after he was charged with his estranged wife's murder. 

During Troconis' latest pre-trial hearing last week, her attorney told the judge that state prosecutors had given him documents from the investigation that indicated that law enforcement suspected that Fotis Dulos' friend Andreas Toutziaridis helped him create an alibi for his wife's disappearance.

Court documents detail that federal investigators wanted to search Toutziaridis' cellphone and that the cellphone was seized by agents at Newark Airport in New Jersey a month after Jennifer's 2019 disappearance.

Court documents reveal Toutziaridis flew from Greece to stay with Fotis at his Farmington home when he was stopped by authorities who seized his phone.
