A Baltimore City jury convicted Shawn Stevenson today of first-degree murder and possession of a deadly weapon with the intent to injure for murdering the mother of his children in Northeast Baltimore last year.

On April 23, 2012, Somchanh Sipayboun was found dead in a home in the 5400 block of Hilburn Avenue. She had been beaten, her spine and collar bone broken, bound with duct tape, sexually assaulted, strangled, and stabbed 14 times. 

The investigation revealed that Sipayboun and Stevenson had been in a 13-year relationship. They had been having problems and fighting in the previous few months.  Sipayboun decided to leave Stevenson and moved to the home on Hilburn Avenue with her children and sister.  She and Stevenson owned the house but it was up for sale. On April 23, Stevenson told her that there was a contract on the house and that she had to get her stuff out of the home immediately. Sipayboun called her sister to help her and went to the home. Her sister arrived an hour later and found her in the bathtub dead and naked with the shower running. 

Police tracked the cell phones belonging to the defendant and victim and found that they were both pinging off of a cell tower near the home during the time of the murder. Both phones were taken to Dundalk after the murder. Sipayboun’s phone was found in a drain pipe, and Stevenson’s phone was tracked to the location where he was originally detained. 

There was a duct tape roll on the kitchen counter of Stevenson’s home that had similar characteristics to the tape that Sipayboun had been bound with. 

Scheduled for sentencing on October 30, 2013, Stevenson faces the possibility of two life sentences.

Assistant State’s Attorneys Amy Donze and Roya Hanna prosecuted the case.
