A teenager in Texas was last week charged with capital murder for fatally shooting a Kenyan four times.
The American, Patrick Wayne Kemp, 18, was charged with capital murder.
Authorities say Mr Kemp has made a name on the internet as a brash, young Twitter pornographer,
He is accused of luring the Kenyan man to a park and shooting him in the bathroom, then stealing his car and credit cards.
James Thotho, 37, was shot four times in the bathroom.
According to an investigation by a US television station, Mr Kemp has a large following on social media, with over 38,000 people following his X-rated Twitter account and another 5,000 people on Facebook.
Police in Texas believe that Mr Thotho was not his first victim and think the suspect has robbed other victims.
Mr Kemp is being held with no bond at the Harris County Jail.
