A California woman has filed a lawsuit against a former male ultrasound technician and the hospital he worked at on allegations of rape.

Identified as Jane Doe, the woman filed the suit Monday in San Manteo County Superior Court against Shukrat Saydaliyev and San Mateo County Medical Center, accusing him of sexually assaulting her while she was medicated and in the midst of an ultrasound exam, according to The Palo Alto Daily Post.

“Plaintiff was traumatized and felt frozen," according to the suit. "She felt weak from the medicine and was scared to tell anyone what happened."

The event is alleged to have taken place on March 8, 2017 when Doe, who felt ill, admitted herself to the hospital where a nurse ordered an ultrasound exam for her. Prior to the procedure, she was administered an unknown medication, which along with her ailment, made her feel weak.

Doe was left alone with Saydaliyev for an hour and 16 minutes, during which time he performed a stomach ultrasound on her before applying lubricant to her private area and began conducting a vaginal ultrasound which lasted about 30 minutes.

Doe claims that during the vaginal exam, she asked if she could relax and close her legs but that Saydaliyev told her no and continued touching her private area after the procedure ended, eventually raping her. He then wiped Doe off with towels and covered her with a sheet, according to her suit.

Doe returned to the hospital the next day with her husband to report the attack. Attendees alerted the police who arrested Saydaliyev for the rape of an intoxicated person and sexual battery. Saydaliyev, however, was not charged and released from jail due to lack of corroborating evidence, according to San Mateo County District Attorney Steve Wagstaffe.

“It came down to her word against his, and there was no corroborating evidence,” Wagstaffe said. “I’m not at all saying that this didn’t happen. But we need to prove things beyond a reasonable doubt, and since he denies this happening, it creates a reasonable doubt.”

Doe claims the attack has left her with feelings of insomnia, depression, nightmares and anxiety, as well as the need for a therapist and medication to support her mental state. Her suit accuses the hospital of acting improperly by allowing an ultrasound technician to examine a patient of the opposite sex without someone else in the room, and of hiring Saydaliyev without a background or reference check.

“Defendants failed to fulfill their legal duty to provide a reasonably safe environment for female patients,” the suit alleges. “As a result of defendant’s negligent, careless and reckless acts and omissions, Jane Doe was improperly touched by a depraved predator, who exploited his position as a medical technician to violate an innocent and unsuspecting woman.”

Under similar allegations, former male ultrasound technician Kevin W. Ryan from Omaha, Nebraska cut a plea deal in 2016 in a case involving accusations of rape against him by three female patients in the last months of 2011. As part of the agreement, Ryan was sentenced to up to five years behind bars but was not required to register as a sex offender.

Victims of rape or any form of sexual assault are advised to undergo examinations to collect DNA evidence within 72 hours of such attacks. In addition, the act of bathing, changing clothes or cleaning oneself in any way reduces the likelihood of finding any evidence that can hold up in court, according to the Rape Abuse and Incest National Network. It is unknown if Doe had requested such an exam at the time of the crime.

Saydaliyev left the medical center in April 2017 and no longer works for San Mateo County. San Mateo County counsel John Beiers supports the actions taken by the hospital upon learning of the alleged event.

“The Medical Center took this allegation very seriously and will always strive to put patient safety first,” he said.
