RIP

The man arrested in connection with the death of an actress from "Step Up" has officially been charged with murder.

29-year-old Adrian Johnson was just slapped with a first degree murder charge Tuesday after Tricia Lynn McCauley was found dead in her car in Washington D.C. the same morning.

The medical examiner's office reportedly determined she died from asphyxia -- strangulation.

As we reported ... cops say Johnson and McCauley did not know each other. It could be a carjacking ... cops say Johnson was seen driving Tricia's car.

Tricia was a stand-in for Jenna Dewan Tatum in "Step Up" in 2006, as well as a yoga instructor in the D.C. area. She was 46.

Carrie Fisher died Tuesday morning ... days after suffering a massive heart attack on board a flight from London to LAX ... a family spokesperson has confirmed.

TMZ broke the story ... Fisher was on a flight from London to LAX Friday when she suffered the heart attack 15 minutes before landing. People on the plane tell TMZ she appeared lifeless.

A passenger who's an EMT performed CPR on Carrie and once the flight landed, paramedics rushed her to UCLA Medical Center where she remained in intensive care until her death.

The family had said she was in "stable condition" but we're told she was not responsive after her medical emergency.

Carrie had been on a publicity tour for her new book, "The Princess Diarist." The book recently made headlines because she wrote about having an affair with co-star Harrison Ford while shooting the original 'Star Wars' movies.

Of course, Princess Leia was her iconic role, but Carrie also starred in "The Blues Brothers," "When Harry Met Sally," "Postcards from the Edge" and many, many more.

She famously battled substance abuse throughout her life. In 2013, she was hospitalized for complications from bipolar disorder.

Carrie is survived by her mother, Debbie Reynolds, daughter, Billie Lourde, brother, Todd Fisher, and sisters Tricia and Joely Fisher. Billie made an appearance alongside her mom in 'The Force Awakens.'

J.J. Abrams, director of 'The Force Awakens,' just said it all ...

Carrie Fisher was a kid at heart, especially when she got a hold of a squirt gun ... so says Chewbacca, who was there when it happened during the filming of 'Star Wars.'

Peter Mayhew joined "TMZ Live" Tuesday to share his favorite memory with Princess Leia ... going rogue on the cast with a squirt gun and soaking everyone ... including Harrison Ford and Mark Hamill.

Carrie Fisher's last film will not be compromised as a result of her death ... TMZ has learned.

An official from Lucasfilm tells us Carrie was "absolutely wrapped" for "Star Wars: Episode VIII."

The official added it's too early to tell how Carrie's passing will impact future installments of the franchise.

Fisher plays General Leia Organa in 'VIII.' The movie's official Twitter account said they wrapped back in July.

Carrie Fisher never improved from the time she was rushed to UCLA Medical Center ... sources familiar with the situation tell TMZ.

We're told she was unresponsive from the time she suffered the massive heart attack on the United flight to the time she died. When reports surfaced she was in "stable" condition the reality was her condition did not improve.

TMZ broke the story, Carrie went into cardiac arrest Friday ... 15 minutes before her plane landed at LAX. Passengers on the flight told TMZ Fisher seemed "lifeless" on the flight and we're told it took a good 10 minutes to get a pulse back.

Carrie succumbed Tuesday morning at UCLA Medical Center.
