Manhunt underway for 'extremely dangerous' convicted felon suspected of killing a 26-year-old female tech CEO in Baltimore

Baltimore police are scrambling to find an "extremely dangerous" man suspected of killing 26-year-old tech CEO Pava LaPere, who was found dead in an apartment building Monday.

The suspect, 32-year-old Jason Dean Billingsley, should be considered armed and dangerous as he is wanted on charges of first-degree murder, assault and other offenses in connection to LaPere's death, acting Baltimore Police Commissioner Richard Worley said Tuesday.

LaPere, co-founder of the small startup EcoMap Technologies, was reported missing Monday morning, police said. Hours later, police were called to a downtown apartment building, where LaPere was discovered with signs of blunt-force trauma to her head, Worley said.

The young tech executive, who had been featured in this year's Forbes 30 under 30 list for social impact, is being mourned as an innovative leader who was devoted to supporting those around her.

The building where she was found had security measures that would have required someone to "allow the (suspect) in the building," Worley said.

Investigators think Billingsley is still in the Baltimore area and urge anyone who has information on him or his whereabouts to call 911 immediately, Worley said Tuesday.

"This individual will kill, and he will rape," Worley cautioned, citing the suspect's criminal record. "He will do anything he can to cause harm."
