approximately 6:52 p.m. Thursday Madjour “violently and unexpectedly attacked the victim” – inflicting life-threatening wounds to the head.

Detectives said Madjour and 60-year-old Harry Swayne III of San Pablo knew each other and were both working as security guards at the construction site. Arriving officers and medical personnel worked to save Swayne, but said he was pronounced dead at the scene. Police said Madjour was taken into custody at the scene and the suspected murder weapon, a long metal pole, was taken into evidence.

Madjour was arrested for murder and transported to the John Muir Medical Center where he was treated for minor injuries. It was not revealed how he sustained those injuries. Madjour was ultimately transported to the Martinez Detention Facility where he was booked and is currently being held on $1,000,000 bail.

Anyone with information regarding this crime is asked to call Walnut Creek Police Department Detective Sergeant Andy Brown at 925-256-3553.

    Walnut Creek is changing fast, and not for the good. It seems it started 2 years ago that I started seeing a lot more street people along with the homeless and suspicious looking types started hanging around.
    I fear it’s only going to get much worse!

    Horrible! Condolences to the victims family. What happened???

    Thank you for the alert last night. We couldn’t believe it when we read it.

    What an awful day.

  6. Audrey Ainselowe on Mar 9, 2018 at 8:47 am

    Speechless.

    Was this a incident between transients or “locals?” In the absence of mental health and/or drug issues, its hard to imagine what went down.

      @Chris – That and other questions being asked, Chris. Investigation still in the formative stages but we hope to have more later today.

    I was wondering if this was two transients myself. This was across the street from the Walnut Creek Presbyterian Church. Anything going on at the church last evening?

    Holy crap.

  10. Barbara Windsor on Mar 9, 2018 at 10:35 am

    O no. A wrong word? An insult? Guess we’ll find out eventually. Horrible.

  11. Dan Galloway on Mar 9, 2018 at 10:36 am

    Wow.

  12. Tim Davis on Mar 9, 2018 at 10:37 am

    Awful. Unprovoked attack?

  13. JOAN BETTENCOURT on Mar 9, 2018 at 10:47 am

    Its says in the article they were security guards working the construction zone not transients.

      @Joan – Early theories posted to the earliest version of the story, Joan. They are to be forgiven!

  14. Candy McCorkell on Mar 9, 2018 at 12:42 pm

    What a heartbreaker. Sixty years old working as a construction site security guard, and you get beaten to death by a co-worker with a metal pipe!?! In Walnut Creek? Deep condolences to family and friends of the victim.

  15. Tim Davis on Mar 9, 2018 at 1:41 pm

    It would be interesting to find out how many crimes have been perpetrated by security guards. is it just me or does it seem they have been involved in some serious crimes?

    • NEWS24-680 on Mar 9, 2018 at 1:47 pm

      @Tim – Hmm. We can think of a couple of major crimes, Tim. Interesting thought, with proximity to weapons, control of their space, and familiarity with police procedure coming to mind as possible contributors – though if you boil it down you’d probably find them no more culpable than any other sector of the population.

  16. Kris Kagen on Mar 9, 2018 at 1:42 pm

    Sounds pretty cold blooded on the face of it. Need to know more.

    • NEWS24-680 on Mar 9, 2018 at 1:44 pm

      @Kris – Agreed, Kris.

  17. Dina Alexander on Mar 9, 2018 at 1:42 pm

    My Lord!

  18. Adam Miller on Mar 9, 2018 at 1:43 pm

    Pretty strange. You have to wonder what set him off.

    • NEWS24-680 on Mar 9, 2018 at 1:44 pm

      @Adam – Indeed.

  19. Johnny on Mar 9, 2018 at 5:42 pm

    Seems like security guards aren’t vetted any better than transients.

  20. Tricia Yung on Mar 9, 2018 at 10:52 pm

    I take it these were unarmed security guards? Hence the metal pole wapon?

  21. Dan Gephardt on Mar 9, 2018 at 10:55 pm

    What a crappy couple of days. Now Yountville. It’s a good thing I don’t drink.

    It is worse! People who look like YOU and ME are killing people. Your prediction model is not so good.

  23. David on Mar 10, 2018 at 10:36 pm

    And YOU are stoking fear of the OTHER. Nice work. Charitable work. Jesus would love it!

  24. Lori Atmaine on Mar 11, 2018 at 11:34 am

    SOMETHING triggered this. Or do people really go crazy and kill other people without reason all the time?

  25. Alice Onikuza on Mar 11, 2018 at 3:50 pm

    Horrible. Thankfully not something we see often here.

  26. R. Prescott on Mar 11, 2018 at 3:51 pm
