Charges have been upgraded against a former Sikh temple leader accused in the fatal beating of his wife.

The Integrated Homicide Investigation Team says Narinder Kaur Kalsi was taken off life support Sunday afternoon, with her family at her hospital bedside.

It comes a week after she was found critically injured in her Surrey, B.C., home.

Her husband Baldev Kalsi was originally charged with attempted murder but those charges were upgraded to second-degree murder on Monday morning.

Kalsi, 66, was the president of the Brookside Sikh temple, but was removed from his position after charges were laid.

The congregation at the temple says they are heartbroken because Mrs. Kalsi would attend almost every day.

Surindar Jabal of the Brookside Gurdwara Society remembers her as a tireless volunteer.

“Whatever work was needed she was always here,” he said.

“She was here all the time here and she prepared food for all the volunteers. So we are missing her dearly. She was [a] very important part of this Gurdwara.”

Her husband remains in custody until his next court date on Aug. 6.

Mounties are investigating an incident last Tuesday after he was assaulted at the Surrey Pre-Trial Services Centre. The beating left him with facial injuries, but it’s not believed the incident is connected to his wife’s murder.
