A 21-year-old California man was arrested on suspicion of murdering his mother, a longtime beauty professional who ran her own skincare studio in Los Angeles.

Yana Landau was found stabbed to death inside her Glendale home Monday evening, police said.

Sebastian Landau is accused of killing the 55-year-old woman, whose body was discovered with multiple stab wounds at a residence in the 500 block of Justin Avenue.

An autopsy of her body is currently scheduled, according to the County of Los Angeles Medical Examiner.

Her son is now being held on $2 million bail, according to the Los Angeles County Sheriff’s Department.

Glendale police were called to the family’s home around 6 p.m. Monday after someone reported discovering blood inside the residence, according to a statement released by the department Tuesday.

Officers entered the property and found Yana suffering from multiple stab wounds. She was pronounced dead at the scene.

As investigators searched the surrounding area, they encountered a young man sitting inside a parked vehicle nearby.

The man was identified as Sebastian Landau, whom police determined was Yana’s son and the sole suspect in her killing.

Investigators also recovered a weapon believed to have been used in the deadly attack, though authorities did not specify what kind of weapon was found.

Police have not disclosed a possible motive or said what may have preceded the fatal stabbing.

Yana was a licensed esthetician with more than 25 years of experience in the beauty industry and operated a business bearing her name, where she offered eyelash extensions, permanent makeup, microblading, waxing and skincare treatments.

According to her business website, she graduated from the Aveda Institute in New York and worked at upscale salons in New York City and Miami before establishing her practice in Los Angeles.

She had also continued her professional education, receiving advanced training in chemical peels and other beauty treatments, and was pursuing additional studies in nursing.

Her social media accounts offered a glimpse into her personal and professional life, featuring photos with friends and her family, including her son, along with numerous posts showcasing her beauty services and work with clients.

According to her Facebook profile, she was divorced.

The investigation remains ongoing, and authorities are asking anyone with information to contact the Glendale Police Department at 818-548-4840.
