Olathe fentanyl dealer sentenced in woman’s disappearance. She planned to go to FBI
A man charged in connection with the disappearance and death of a Kansas City woman who went missing in 2022 was sentenced to six years in prison Friday.
Jacob Block, 28, of Olathe, had already been sentenced to 20 years in prison in a federal case in January 2025 after he pleaded guilty to a pair of charges related to the distribution of fentanyl. Court records indicate he is serving his sentence at a federal prison in Georgia.
Block pleaded guilty to a pair of felonies in Jackson County Circuit Court on Friday, one count of accessory abandonment of a corpse and one count of accessory tampering with physical evidence, and was handed the six-year sentence. A judge ordered that the sentence be served concurrently with his federal term.
Block’s attorney, Angela Hasty, did not immediately respond to a request for comment Monday afternoon.
Block and Eunice Carlo-Martinez, of Kansas City, were both charged in January 2025 with one count of accessory abandonment of a corpse and one count of accessory tampering with physical evidence, related to the death of Abbi Schaeffer. The Jackson County case against Carlo-Martinez is still pending, and a warrant for her arrest remains active.
Schaeffer was last heard from on May 23, 2022. Ring camera footage showed her leaving her Clay County home and getting into a vehicle, according to court documents. Police checked a Kansas City home at her last known location broadcast by the Life360 location-sharing app, but were unable to contact anyone there.
Police retrieved security footage from the home, which showed Block, Carlo-Martinez and Schaeffer entering the residence but did not show Schaeffer leaving, according to court documents. A few days after Schaeffer disappeared, Block and Carlo-Martinez could be seen on camera using a dolly to move a large “box-like object” to a U-Haul.
In April 2023, skeletal remains were found in a box in a ditch along Blue River Road, and investigators said the box appeared to look like what the two had been taking to the truck. Dental records confirmed the remains were Schaeffer’s.
Police said messages on Block’s and Carlo-Martinez’s Facebook accounts indicated that they gave Schaeffer fentanyl and that she overdosed.
Abbi Schaeffer’s mother, Belinda Schaeffer, told The Star in 2023 that her daughter had told her she had information about a fentanyl trafficking operation and that she was supposed to talk to the FBI before she disappeared.
In the federal case, Block was among a group of 13 people who investigators linked with a conspiracy to distribute fentanyl.
In a court filing in January 2025, Assistant U.S. Attorney Maureen Brackett wrote that Block had distributed “at least 63,000 potentially lethal doses of fentanyl, at 0.1 gram per dose. The investigation of his crimes uncovered evidence establishing that defendant is a significant danger to the community, including through his involvement in the death of one of his buyers, his abandonment of his buyer’s body on the side of the road in Kansas City, Missouri, and his tampering with physical evidence.”
In court documents, Hasty wrote that Block considered Abbi Schaeffer a friend and said that the two of them had suffered from addiction.
“While he can’t change the past, he is determined to change his future,” Hasty wrote. “Mr. Block accepts full responsibility for his actions. He is sympathetic to (Schaeffer’s) family, and is adamant that if he had given anything to (Schaeffer) that would have contributed to her death, he would admit such. He vehemently denies giving (Schaeffer) anything that could have caused her death.”
