Pava LaPere murder investigation timeline: Baltimore CEO may have been killed more than 2 days before her body was found, police say

• Tech CEO Pava LaPere, 26, was found dead at her apartment building on Monday.
• Police believe she was murdered, and a 32-year-old man has been arrested in connection to her death.

Young Baltimore, Maryland, tech CEO Pava LaPere was found dead at her apartment building this week. A 32-year-old man was arrested Wednesday night and charged in connection to her death.

On Thursday, Baltimore Police Department acting commissioner Richard Worley said that investigators believe LaPere was likely murdered days before her body was discovered.

Here's what we know about the investigation so far:

LaPere was found dead on Monday

LaPere was 26 years old when she was killed. She was the founder and CEO of the startup EcoMap Technologies and was recently named on the Forbes 30 Under 30 list.

She was reported missing sometime Monday, hours before her body was found, police have said.

At 11:34 a.m. Monday, Baltimore Police Department officers went to LaPere's apartment to investigate. They were led to the roof by a colleague of LaPere's who reported finding her body.

They observed signs of blunt-force trauma on her body.

Jason Billingsley, a convicted sex offender, was arrested in connection to LaPere's death

Authorities said Tuesday that 32-year-old Jason Billingsley was a suspect in connection to LaPere's death.

He's a convicted sex offender who was released from prison early.

Baltimore state attorney Ivan Bates described Billingsley as a "repeat violent offender." And Worley, the acting police commissioner, said that "this individual will kill and he will rape. He will do anything he can to cause harm."

Billingsley was arrested late Wednesday on charges that include first-degree murder, assault, and reckless endangerment.

Officials believe LaPere was likely killed more than two days before she was found

On Thursday, Worley said investigators believe LaPere was likely killed on Friday night — more than two days before she was found dead.

Surveillance footage showed LaPere entering her apartment building on Friday night around 10:30 p.m., according to court documents obtained by Insider.

Afterward, a man identified by authorities as Billingsley was seen walking up the front steps of the building and waving down LaPere. The two can be seen walking into an elevator together, investigators said, citing security footage.

About half-an-hour later, footage then showed the man police believe to be Billingsley leaving the building wiping his hands on his shorts, investigators wrote in the documents.
