A pregnant woman has admitted leaving the scene of an e-scooter crash that tragically killed a young brother and sister. 'Selfless' 16-year-old Roman Casselden and his 'wonderful' nine-year-old sister Darcie died after a collision in Pitsea, Essex, in February last year. Deimante Ziobryte was tearful and visibly shaking as she admitted leaving the scene of the fatal crash. The 21-year-old, from Benfleet in Essex, was warned by magistrates that she could face a prison term for the offence.
