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