BALTIMORE — We're learning more about the background of a man who allegedly murdered a young tech CEO inside her Mount Vernon apartment building.
Jason Dean Billingsley, 32, has an extensive criminal history dating back to 2009.
He's a registered sex offender who was convicted in 2015 of sexually assaulting a woman in West Baltimore back in 2013.
In that case, Billingsley was found guilty of strangling and threatening to shoot the victim when she refused to have sex with him.
He was sentenced to 14 years in prison but released in October 2022 due to credits earned for good behavior.
Since then police say he's suspected of committing a string of other violent crimes.
An arrest warrant was issued September 25, charging Billingsley with stealing a handgun in Baltimore County.
Detectives then linked him to a September 19 arson and rape at a residence on Edmondson Avenue.
Charging documents indicate Billingsley was a maintenance worker at the location.
That day he allegedly broke into a home on the property, and bounded a woman and her boyfriend at gunpoint.
Billingsley is accused of slashing and raping the woman, before setting the couple and their apartment on fire.
As result each victim suffered second and third degree burns to the body. Police say the couple was targeted, but wouldn't specify why.
Detectives identified Billingsley as the suspect through surveillance footage and several pieces of evidence left behind at the scene.
Among those items, police found a knife, handcuffs, duct tape, and a hoodie that Billingsley reportedly wore on camera the previous day.
A gas can, lighter and bleach dampened towels were also recovered nearby.
It was some of that evidence which connected Billingsley to Pava Marie LaPere's death.

On September 25 police discovered the 26-year-old Johns Hopkins grad dead on the rooftop of the Congress apartments on W. Franklin Street.
The medical examiner ruled she'd died from strangulation and blunt force trauma to the head.
Charging documents suggest the murder occurred sometime between 10:32 and 11:08pm on September 22.
Surveillance footage shows LaPere letting a man believed to be Billingsley into the lobby of the complex.
Both were seen getting on the elevator together, although it's unclear if they actually knew each other.
Billingsley is observed in the stairwell leaving the building about half-an-hour later.
The following Monday LaPere was reported missing leading police to the gruesome discovery.
LaPere was known as the founder and CEO of EcoMap Technologies, a Baltimore-based start-up tech company.
Billingsley was arrested September 27 at a train station in Bowie. Baltimore City State's Attorney Ivan Bates confirmed he is still on parole and probation.
He now faces life in prison without parole if convicted.
