A 36-year-old repair technician was killed while on a service call Friday night, and her customer was arrested two days later in connection with her death.

Lyndi Lee Fisher, a wife and mother of three children, was a technician for Arrow Appliance of Lancaster, California, a city about 70 miles north of Los Angeles.

According to a statement from the Los Angeles County Sheriff’s Department, William Hughes, 30, was arrested on Sunday on suspicion of Fisher’s murder, and is being held on $2 million bail.

KTLA5 reports that Fisher was called around 6:00 pm to repair a refrigerator at Hughes’ home in the 43200 block of Doverwood Court in Lancaster. She was found unresponsive in the residence about 5 hours later at 11:11 pm, and was pronounced dead at the scene. According to authorities, the victim sustained blunt force trauma to the upper body.

Hughes was reportedly the sole occupant of the home, which is owned by his family.

The suspect initially told police investigators that he had briefly left his home while Fisher was repairing the appliance, and found her unresponsive on the floor when he returned.

Christy M. Savoie-Knop, the owner of Arrow Appliance, told KTLA5 that Fisher had visited the home once before during the prior week to assess the repairs.

According to Savoie-Knop, there was no indication from her employee that there was anything troubling about her previous interaction with the customer.

Local CBS affiliate KCAL9 spoke to two of Fisher’s children, 9-year-old Violet Fisher and 13-year-old Trinity Fisher, who tearfully told reporters that her mother was her best friend and “always made me smile.”

Fisher’s employer has set up a GoFundMe account to help her family.

A statement on Arrow Appliance’s Facebook page said the company “will miss her bright ray of sunshine every day.”
