SYDNEY -- More than a year after the body of Cassidy Bernard was found in her home on the We'koqma'q First Nation, Nova Scotia RCMP say they will provide an update in the case Tuesday morning.

Police are expected to announce they have made an arrest.

According to Bernard's family, the RCMP have arrested Austin Isadore, the ex-boyfriend of Bernard and father of her twin girls.

It's been both frustrating and heartbreaking as Bernard's family has waited more than 13 months for this day to come.

Mona Bernard, Bernard's mother, says she is happy to have some closure and that, for the first time in a long time, there were smiles on her family's faces.

The 22-year-old Bernard was found unresponsive inside her home on Highway 105 on the We'koqma'q First Nation, N.S., on Oct. 24, 2018.

Her two infant twin girls were also found inside the home. They were dehydrated, but they weren’t injured.

The family and community members have held protests and have appealed for information and answers since her death.

The band council even offered a $100,000 reward if anyone was able to come forward with information that would lead to an arrest.

Police have previously said that Bernard’s death is considered suspicious, but they haven’t said how she died.

A news conference is scheduled for 11 a.m. Tuesday at the community hall on the We'koqma'q First Nation.
