Speaking to NBC San Diego, Saefong remembered her sister as kind, loving and caring.

She told the outlet: 'She was just a beautiful soul inside and out, in every way imaginable. She would absolutely give anything and everything for her son.

'My sister, she worked from home. She was in a Zoom meeting. At that point, she thought someone was trying to break in, and she left. 

'She said, 'Hey, give me a second. Somebody is trying to break into my house.'

When Ashley didn't return, her co-worker decided to contact her mom and when the family failed to reach her, contacted the sheriff's office.

Saefong continued: 'My mom called me just before 11 o'clock, and she was hysterical, saying, 'She's gone. She's gone.' I shouted, 'Who's gone? Who's gone?' 

'She wasn't giving me details. She said, 'Ashley. Ashley's gone, I just know it. We knew [Christopher] was volatile, but we never expected this.'

According to Saefong, the couple had been going through a divorce but her sister denied any physical abuse. 

She added: 'We asked her, 'do you feel like he's physically abusive?', 'No, absolutely not', she would say. She would say, 'He would never physically harm me. He's fine.'

Days prior to the deaths, Christopher Bird had received court documents declaring spousal and child support.  

Saefong said: 'We think the divorce may have sent him over the edge and then along with the custody battle that was finalizing at the end too.'

Following the incident, his father drove to pick him up and took him to stay with another family member.

'We thank the Lord for the life she was able to live and all the lives she was able to touch in her short time on this earth. 

'She leaves behind her 9 year old son who was the love of her life as well as her mother Patti, father John, brother Eric and sister Allison.
