A public vigil will also take place today in Riverdale, Georgia, according to social media updates of Bobbi Kristina's cousin, Jerod Brown.

In development of police investigation, a criminal investigation was launched against Bobbi Kristina's husband, Nick Gordon, according to several reports in CNN, TMZ and People Magazine.

"Brown has certain injuries that needs explanation," according to a report in CNN.

Some vouched that Gordon and Bobbi Kristina weren't really "married" and therefore Gordon should be addressed only as her "boyfriend".

"The police are going to follow the evidence and see where it leads us," says Roswell Police Chief Rusty Grant, in a brief interview with People Magazine.

February 11 marks the 3rd year death anniversary of Bobbi Kristina's mother, Whitney Houston.

Houston was found unconscious in a Los Angeles hotel bathroom and her demise was declared as accidental drowning.  Further reports in the toxicology screen found several drugs in her system.

In a glimpse of coincidence, her daughter Bobbi Kristina was found in the same circumstance almost three years later. The only difference is that Bobbi Kristina is still in an induced medical coma.

During Clive Davis' yearly Pre-Grammy party, Magic Johnson paid homage to Bobbi Kristina by addressing a 10 second silence on her behalf, right before officially introducing Clive Davis.

"10 seconds for Bobbi Kristina," the former NBA star said, while surprised at the same time how the room quickly fell into silence.

"That's hard in Hollywood, to get 10 seconds of silence," Johnson further added.

Aside from friends, acquaintances and relatives, people from other parts of the world also paid homage to Bobbi Kristina through Facebook and Twitter.
