Marybeth Tinning: The Horrible Serial Killer

Marybeth Tinning: The Killer

Marybeth Roe Tinning (born September 11, 1942) is an American serial killer. In 1987, Tinning was charged and sentenced for the murder of her ninth child, 4-month-old daughter Tami Lynne, on December 20, 1985. Laboratory testing demonstrated her casualty resulted from asphyxia by suffocation. Marybeth is suspected to be also involved in the premature casualties of her eight children.

Tinning And Victims

Nine Tinning children perished under Marybeth’s care over 14 years. The reason for death for the first eight children was originally guessed to be genetic. Even when their 1978 adopted sixth child Michael, who was not of blood connection, perished in 1981, authorities failed to open an inquiry into his death. After analyzing the other children’s casualties, the Schenectady County prosecutors only had sufficient proof to arrest Tinning in one child’s casualty. In July 1987, she was sentenced to second-degree murder and convicted to 20 years to life. A plea of her case to the New York Supreme Court contended Tinning’s admission to the crime was coerced and there was insufficient information to convict her, but this plea was rejected.

Tinning’s diagnosis of Munchausen syndrome by proxy (MSP) has come into suspicion. It is doubtful if she has ever been diagnosed with MSRP. Analyzing her recurring events, some think Tinning’s pattern of behavior aligns flawlessly with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition’s (DSM-5) Development and Course section on the disorder: “In people with recurrent episodes of falsification of signs and symptoms of disease and/or induction of injury, this pattern of consecutive deceptive contact with medical personnel, including hospitalizations, may become lifelong.”

Tinning was detained at Taconic Correctional Facility for Women in Bedford Hills, New York. She was refuted parole six times, but was permitted parole at her seventh hearing in July 2018 and was released on August 21, 2018.

Marriage and Poisoning

In 1963, Marybeth met Joseph Tinning on a random date with some friends. Joseph was quietly happy-go-lucky. They were wedded in 1965 and their first kid, Barbara, was born in May 1967, followed in January 1970 by Joseph Jr. In October 1971, Marybeth’s dad perished of a sudden heart attack.

In 1974, Marybeth’s spouse Joseph was admitted to the hospital with a near-fatal case of barbiturate poisoning. Later, he and Marybeth realized that, when this occurrence occurred, their marriage was in huge turmoil. This led to her placing barbiturate pills, which she took from a friend with an epileptic daughter, into Joseph’s grape juice. Joseph refused to press charges against his wife.

Children’s deaths

On December 26, 1971, Jennifer, the Tinning’ third kid, was born at St. Clare’s Hospital. Jennifer had hemorrhagic meningitis and numerous brain abscesses that had evolved in utero. Jennifer lived for only a week and never left the hospital; she perished on January 3, 1972.

Two weeks after Jennifer’s casualty, Tinning took two-year-old Joseph Jr. to the Ellis Hospital emergency room in Schenectady, contending that he had experienced a seizure and choked on his vomit. Joseph Jr. kept up in the hospital for many days under observation before being released when doctors discovered nothing wrong with him. On January 20, a few hours after his release, Marybeth brought Joseph Jr. back to the Ellis Hospital emergency room. The boy was lifeless on arrival, and his casualty was attributed to cardiopulmonary arrest.

Numerous weeks later, on March 1, Marybeth hurried Barbara, almost five years old, to Ellis Hospital because she had gone into convulsions. The next day, Barbara perished after being in a comatose state for many hours; her demise was attributed to Reye syndrome. Marybeth Tinning was 29 at this time.

On Thanksgiving Day 1973, Tinning gave birth to son Timothy; on December 10, Timothy was brought back to the same hospital, dead. Tinning said doctors discovered him lifeless in his crib. Doctors associated his casualty with abrupt infant death syndrome (SIDS). In March 1975, Tinning’s fifth kid, Nathan, was born; that autumn, he perished in the car while out with Tinning.

In August 1978, the Tinnings adopted newborn Michael; on October 29, Marybeth gave birth to her sixth kid, Mary Frances. In January 1979, Tinning hurried Mary Frances to the emergency room, immediately across the street from her apartment, telling the baby was having a seizure. The staff was eligible to revive her, reporting “aborted SIDS.” A month later, Tinning came back to the hospital with Mary Frances in full cardiac arrest; she was revived but had an irreversible brain defect. She perished two days later after being taken off life support. The Tinnings’ eighth kid, Jonathan, was born in the fall of 1979; he perished in March 1980, after being kept on life support in Albany, New York for four weeks.

In February 1981, Michael fell down the stairs and underwent a concussion. On March 2, Tinning took him to the doctor because he wouldn’t wake up. Michael was already lifeless when Tinning brought him into the doctor’s office. Since he was adopted, the long-suspected assumption that the casualties in the Tinning family had a genetic origin was eliminated.

Tami Lynne was born on August 22, 1985; on December 20, she perished from being smothered. On that day, the Tinnings were toured by Betsy Mannix of Schenectady County’s Department of Social Services and by Bob Imfeld of the Schenectady Police Department, about Tami Lynne’s casualty.

The reasons for the children’s casualties were listed diversely, between natural, doubtful, or sudden infant death syndrome. Six autopsies of the Tinnings’ kids took place after Tami Lynne’s casualty, but they did not disclose any indications of abuse. There were uncertainties and community murmurs of foul play. Before Tami Lynne’s death, there had been no suspicion discovered in the sequence of casualties. “There were numerous of us in on it, I guess,” said Dr. Robert L. Sullivan, Schenectady County’s Chief Medical Examiner. “If anyone is negligent, I presume I am. I possibly should have said, ‘There must be more to it than this.’ But we all guess, and don’t do.”

Arrest and interrogation

Marybeth and Joe Tinning were individually taken to the Schenectady Police Department for querying about Tami Lynne’s casualty. During the police query, Marybeth signed a document admitting that she had killed Tami Lynne, Timothy, and Nathan. She was arrested and accused of Tami Lynne’s killing.

Police officials originally doubted that Tami Lynne perished of SIDS. Dr. Michael M. Baden, the lead forensic pathologist and member of the State Police’s particular forensic unit, inferred Tami Lynne’s casualty occurred from smothering. After accusing Marybeth of Tami Lynne’s death, officials told her that they assumed the deaths of the eight other Tinning children to be doubtful.
Investigators later told that Jennifer’s demise was not suspect because it happened before the baby left the hospital.

Marybeth Tinning made her $100,000 bail payment and was released from detention until her trial date.

Trial and conviction

Parole attempts

Tinning’s first try for parole was in March 2007. At the parole board meeting, Tinning said, “I have to be truthful, and the only thing that I can say to you is that I know that my daughter is lifeless. I live with it every day and have no memory and I can’t think that I harmed her. I can’t tell any more than that.” Her parole was refused.

In late January 2009, Tinning went before the parole board for the second time. She stated “I was going through terrible times,” when she murdered her daughter. The parole board again rejected her parole, stating that her guilt was “superficial at best.” Tinning was able to parole again in January 2011.

At the 2011 parole board hearing, Tinning said:

“After the casualties of my other kids … I just lost it,” Tinning told the board on Jan. 26. “(I) became a broken worthless piece of person and when my daughter was young, in my state of the psyche at that time, I just thought that she was going to perish also. So I just did it.”

She was refused parole again due to her absence of remorse. In 2011, Tinning was favored by people from Georgetown University Law Centre and people she worked with within the thin jail, interpreting her as the “most adoring, most generous, caring person that they have ever met.”

When queried about the killing during her 2013 appearance, she told, “It’s just — I can’t recall. I mean, I know I did it, but I can’t tell you why. There is no reason.” The parole board stated, “This was an innocent, susceptible victim who was entrusted in your care as her mum, and you cruelly disobeyed that trust affecting a senseless loss of this young life.” The board then said, “…discretionary release would so deprecate the harshness of the crime as to weaken respect for the law, as you placed your interest above those of society’s youth.” Her next chance for parole was in February 2015.

The February 2015 parole board again refuted Tinning’s release, discovering that she proceeded to demonstrate no understanding nor any remorse for taking her kid’s life. Tinning was refuted for parole for the sixth time in January 2017. The parole board decreed her to return in 18 months, rather than the prior standard of 24 months.

Tinning, 76, was released on parole on August 21, 2018. She had fulfilled more than 31 years of her 20-years-to-life verdict before being granted parole. Tinning’s husband, Joseph, who helped her throughout her detention, was present for her release. As part of her release, Tinning was to stay under parole supervision for the rest of her life. A Department of Corrections spokesperson asserted Tinning lives in Schenectady County, in upstate New York. She has a curfew and must attend domestic violence counseling.
