Lauren Riggs is a woman who resides in Holby.
At some point, Lauren married Ian Bunce and gave birth to a boy named Rhys in late 2006. However, she began smoking cannabis and experiencing violent psychotic episodes. In August 2007, Lauren attacked Ian, giving him a black eye. Shortly after this, she was sectioned at the Riverbank Psychiatric Unit.
On 15 September 2007, Lauren escaped from the psych unit and climbed through Rhys' window to take him. His grandmother Maureen ordered Lauren to leave before she alerted the police, but Lauren pushed her into a light fixture and escaped with Rhys. Lauren ran to a nearby construction site to hide from Ian, and she unintentionally asphyxiated Rhys whilst trying to keep him silent. She confronted Ian and grabbed a large metal pole; he tried to wrestle it out of her hands, and she bludgeoned and kicked him to the point of unconsciousness.
On the top floor of the Lee Lane multistorey, Lauren prepared to kill herself by jumping off it, but ED consultant Adam Trueman found her and convinced her not to jump. She was taken to Holby City Hospital's emergency department for treatment, but she soon became agitated and insisted that "they" made her attack Ian. A furious Maureen confronted Lauren, and Lauren viciously attacked Maureen after accusing her of taking Rhys and trying to kill her; the hospital staff restrained and sedated her.
In the absence of any medical staff, Maureen secretly took a drugged Lauren to the construction site to reveal Rhys' whereabouts. Maureen rushed towards a cement mixer after hearing a baby crying, but her head was hit by an overhanging excavator bucket, knocking her unconscious. Lauren was delighted to find Rhys in perfect health and took him. (CAS: "Meltdown")
