Lövgren was convicted and sentenced to closed psychiatric threatment at Salberga prison. He went under the name Flickmördaren (the girl killer) because his last two murders were two young girls. He was at the time of this death in 2002 no longer in threatment because of bad health from cancer. He was buried at Sala cemetery.

The novel Mannen på balkongen released by Sjöwall/Wahlöö in 1967 was based on John Ingvar Lövgren and his crimes.
