A 20-year-old De Soto man convicted of a misdemeanor in connection with the death of his girlfriend last year was recently arrested on a warrant alleging he violated his probation.

The Johnson County Sheriff’s Office said it arrested Johnny Landa last week as part of a warrant sweep when 34 other people were also arrested by deputies and Overland Park police.

According to Johnson County District Court records, Landa was charged July 20 with driving under the influence and traveling at an unsafe speed. He also faces additional traffic charges of reckless driving and transporting an open container.

A jury in January had convicted Landa on a charge of misdemeanor vehicular manslaughter for the death of 17-year-old Griselda Del Real, but prosecutors had sought a much stiffer second-degree murder conviction. Landa was also granted a $40,000 appeal bond after the verdict while he appealed the conviction.

According to testimony in the January trial, Del Real became jealous in August 2007 in De Soto when she saw Landa in a vehicle with another girl.

She jumped on the running board of Landa’s SUV while he was backing up. When he drove forward, she fell and suffered a fatal head injury.

A hearing on the probation revocation allegation is next scheduled for Aug. 21.
