The 25-year-old man accused of killing two married seniors in Vancouver earlier this year was arrested Monday just a few blocks from the victims' home.

Rocky Rambo Wei Nam Kam is facing two counts of second-degree murder in the slayings of 65-year-old Dianna Mah-Jones and 68-year-old Richard Jones, who were found dead inside their Marpole home in September.

Police have not said whether the murder was targeted or random, but people who live in the area told CTV News that officers apprehended Kam at a house located blocks away from the couple's.

They said they will sleep easier knowing a suspect is in custody.

Emma Greenhalgh, who lives next door, said neighbours have been wondering if the deaths were random and if it could have been their houses instead of the Jones's.

"We're right here. We're right next door," she said.

But if it was targeted, she can't figure out what the motive might have been.

"What was the connection? I mean, they were a really nice, lovely couple… They gave so much to the community. Especially Dianna. She was a pillar of the community. She's helped a lot of people in their lives."

She said the couple had big hearts and were generous even to those they barely knew.

Greenhalgh said the couple's garage was broken into a few weeks before their deaths, and that stuff was stolen from her backyard around the same time.

"We're finding that there's people hanging around the neighbourhood that maybe aren't from here and that does concern me because this does seem to fit that kind of profile."

The murders shocked the quiet South Vancouver neighbourhood, and prompted a public warning from police to stay vigilant.

Mah-Jones and Jones's bodies were discovered on Sept. 27 after a friend stopped by their home near 64 Avenue and Hudston Street to say hello and noticed something was off.

The couple's 2014 Kia Soul was missing from the property. A neighbour told CTV News she saw someone drive it out of the driveway the night before, and police later located the vehicle a few blocks from the crime scene.

Kam made his first court appearance Tuesday.
