Charges will be dropped against two Shreveport men in connection with two long-standing Shreveport “cold case” murders and one more recent crime, the Caddo Parish District Attorney’s office says.

The men, who are siblings, and the people they were accused of killing, are:

• Jake Robinson, 62, indicted Aug. 5, 2014, in connection with the Feb. 26, 2004 second-degree murder of Harold Bruce Cotton.

• Henry Robinson, 63, indicted April 1, 2015, in connection with the March 20, 1988 second-degree murder of Claudell Staten.

A June 4, 2015 charge of solicitation for murder, based on a March 2015 incident against a witness, also is being dismissed against Jake Robinson.

The crimes for which the Robinsons were charged remain under investigation and they continue to be suspects, but the death of one key witness and questions about the veracity of testimony provided by others led to the decision to dismiss the current charges.

Staten’s body was discovered by a passing motorist on Ellerbe Road north of Robson Road on March 20, 1988. He had been shot several times. Sheriff’s detectives said the 44-year-old man was shot during a struggle inside his moving car. He was left outside on the ground after the vehicle crashed.

On Feb. 29, 2004, Harold Bruce Cotton was found murdered in the back seat of his car located on White Springs Road on the Caddo and DeSoto parishes line.

People with information on the Staten and Cotton homicides should call the Caddo Parish District Attorney’s office, (318) 226-6826.
