The parents of slain Baltimore tech CEO Pava Marie LaPere shared their profound grief Tuesday while urging Maryland lawmakers to end good behavior credits for convicted rapists like the man charged with killing her. Frank LaPere said no family should have to suffer the way theirs has since the September strangulation death of his 26-year-old daughter, who launched tech startup EcoMap Technologies several years earlier from her Johns Hopkins University dorm room. The high-profile killing in Baltimore brought attention the accused’s criminal record and early release.
