Lawyer's chilling new acts after he was freed from jail for spiking pregnant wife with abortion drugs
A lawyer who was jailed last year for spiking his pregnant wife with abortion drugs has been arrested again after violating a protection order.
Mason Herring, 40, was sentenced last February to 180 days in jail for putting an abortion drug, Misoprostol, in his ex-wife's water, which led to the premature birth of their child.
As a result of Herring's actions, his wife, Catherine, became ill, and their child was born with developmental delays.
Herring has since served his sentence, but he was arrested again on Wednesday for twice violating the protection order barring him from coming within 500 feet of his ex-wife, according to the Harris County Sheriff's Office.
Herring was accused of calling Catherine twice on February 11 and waiting in the lobby of his apartment on February 22 when she arrived to pick up their children from a supervised visit.
Then again, on March 23, police alleged Herring pulled up in his car near where his wife was dropping their children off, knowing that she would be within 500 feet of him.
Herring was pictured smiling in his mugshot and was booked into the Harris County Jail on Wednesday.
His bond is estimated at $100,000, and his next court date is scheduled for Thursday, according to online court records.
The case is prosecuted by the Harris County District Attorney's Office, led by the newly elected Sean Teare.
Teare reportedly worked for the same law firm that represented Herring in his criminal case last year, according to local ABC affiliate, KTRK News.
Herring had served jail time after making repeated attempts to drug his ex-wife after he cheated on her and asked for a divorce.
Catherine told the court that her husband had feared 'looking like a jerk' if she gave birth after the affair.
She slammed the court for his low sentence, claiming that 180 days wasn't enough for her husband's attempt to 'kill' his child on 'seven separate' occasions.
'For two years, my husband has overtly denied this assault, and I'm grateful today that he has finally admitted to his guilt,' she said at the time.
Herring was initially charged with forcing induction to have an abortion but, admitted guilt to a lesser charge of assaulting a pregnant person.
He also admitted guilt to injuring a child under 15. Their child was born prematurely as a result of the abortion medication.
Catherine said their daughter had to spend months eating through a feeding tube and attended multiple therapy sessions for her developmental delays.
His wife testified that she believed Herring had started drugging her in March 2022 when she noticed a glass he gave her was clouded.
The two were on vacation and had separated, but were still in couples therapy. Catherine said it was in a session where she revealed her pregnancy, and he reacted negatively.
Catherine became violently ill and went to the hospital after she started to bleed and her urine turned black.
She said the attempts to drug her continued, and she repeatedly found unsealed orange juice cartons.
Catherine then began to collect evidence against her husband and stopped consuming anything he gave her.
Herring was convicted on two charges of assault of a pregnant person and injury to a child under the age of 15. He served 180 days for the crime
The samples she collected were sent to a lab, where it was revealed that at least two contained the abortion drug.
Catherine also installed cameras in her home and caught Herring taking out a substance in a Ziploc bag and placing it in a cranberry juice drink.
She went to the police in April 2022 and said she wanted to pursue charges against her husband for poisoning.
A protective order was issued that year. Herring hasn't issued a plea on the new charges filed against him.
