Federal investigators said the son of a Lutz fertility doctor tricked his ex-girlfriend into taking a drug that induced an abortion.
John Welden, 28, was denied bail at a hearing Wednesday on a first-degree murder charge.
Investigators said Remee Lee, 26, had wanted to carry their baby to term even though the couple was no longer together. Welden took Lee to his father's fertility clinic, where the couple learned the fetus was six weeks along.
Prosecutors say Welden told Lee to take amoxicillin tablets, saying his father wanted her to do so for the baby's sake.
Court documents allege Welden actually gave Lee Cytotec, a drug that causes women to go into labor.
A few days later, Lee lost the pregnancy.
Now Welden, who worked as a manager at his father's office, is facing murder charges. He faces life in prison if convicted.
Welden's family refused to comment about the case. Neither did Lee's lawyer, who also filed a civil suit in federal court alleging battery and emotional distress.
Lee's attorney did say they may add more people to the civil suit who they believe had liability in the death of the fetus.
