When I saw the reconstruction of his clothing on the NCMEC website a few months ago, I thought of the Teen Trucker entry on Randy Krafts list which is thought to be in reference to Malcolm Eugene Little (who was 20 years old at the time of his death).
NamUs UP # 4282/2433UMCA was briefly in The Region in the April 15, 1983 Los Angeles Times. While NamUs and the Doe Network dont disclose a cause of death for this UID, the Los Angeles Times says He apparently died of stab wounds. It sounds as though he was there for quite some time [due to the fact that they have dental information for the UID yet don't know what color hair he had?].
While most of Randy Krafts victims were strangled, one victim, Roland Young, cause of death was stab wounds in June 1978. This is the article that appeared in the Orange County Register on June 20, 1978 about Roland Gerald Young's murder.
Unfortunately, I haven't had as much time as I would have liked to look into the unidentified lately, but I have noticed that Los Angeles County has updated the case files for many UIDs from the early 1980s. There are a few unidentified young men who were found near freeways during this time period who were updated, yet there still isn't enough information to determine if they were victims of foul play. So far I haven't been able to find them cross referenced in the Doe Network --
NamUs UP # 4318
https://identifyus.org/en/cases/4318 was found behind 5623 Hollywood Blvd. in Hollywood, CA 90028 on December 28, 1981. The address currently is a Thai restaurant called Rodded and has been there for many years (over 25 years per Yelp); prior to being Rodded, it was called Lees Thai and Chinese Food (circa July 26, 1977); Im not sure if it was anything else in between. The address is about two blocks from the Hollywood (101) Freeway. The victim is a slightly built (67, 107 lbs) white male between the ages of 18 to 22 with brown hair and brown eyes.
NamUs UP # 4367
https://identifyus.org/en/cases/4367 15 - 18 year old white male found on September 26, 1980 found at 2152 Ewing St, Los Angeles, CA 90039 (less than a block from the Ventura Freeway).
NamUs UP # 4294
https://identifyus.org/en/cases/4294 25 - 35 year old white male found on October 16, 1982 found at 341 N Mission Rd, Los Angeles, CA 90033 (near the San Bernardino and Santa Ana Freeways, not far from where William Bonin's victim, Charles Miranda was found in 1980). I also noticed that this UID was found east of the the Little Tokyo neighborhood of Los Angeles; I wondered if the "Hari Kari" victim on Randy Kraft's list was found in Little Tokyo?
