SACRAMENTO (CBS13) — The suspect in a Midtown murder is in the custody of the U.S. Border Patrol.

Mohammad Joseph Khan was detained by the U.S. Border Patrol, according to the Sacramento Police Department.

Khan is wanted for the murder of Kelsey Snyder in her Midtown apartment near 17th and P streets.

Police declared Khan a suspect in the June 28 homicide on Tuesday, saying they believed he was armed with a gun and possible heading for Mexico.

On July 4, Khan had posted a message on the CBS Sacramento Facebook page that expressed regret over Snyder’s death.

I loved Kelsey and no one will ever know how much. I wish I never went to see her that night and I know so does everyone else. I was drunk and **** knows she put two pills in my mouth, I started to spit them out but Kelsey told me to take them, because she did too, everything after that was a blur. Anyone that knows me knows I´m not that person. Every day I cry for her and try to kill myself. I want to wake up from this nightmare. Everyday I’m alive I live in misery with what I did to her and everyone else. She was one of the most elegant, beautiful, unselfish, kindest, intelligent, fun, witty, best dressed, loyal, and classiest people in the world. I know 100% there is no god because why would he let this happen to such a person. This society should let the people that want to commit suicide do it in an acceptable manor. I loathe this life. I really hope today it will happen, and if you think it´s that easy you never tried to choke yourself to death. Everyone I asked to help me kill myself would not and told me to run away, I never meant to be on the run. I can´t sleep and drink until I pass out. I wish I was at her grave right now maybe that will give me courage to do it. I´m so sorry for everyone I hurt especially big B. I robbed the world of a precious person. She made everyone´s life better. I want to turn myself in and answer any questions, but I rather try to end my life ASAP.
