The parents of a 23-year-old man allegedly killed by an off-duty Los Angeles police officer last year in Pomona last year sued the ex-lawman and the city Thursday.

Salome and Lidia Rodriguez, the father and mother of Salome Rodriguez Jr., filed the lawsuit in Los Angeles Superior Court. The suit alleges wrongful death, civil rights violations, excessive force and unreasonable seizure, assault and battery and survivorship. The suit seeks unspecified damages. A representative of the City Attorney's Office did not immediately reply to a call for comment.

Rodriguez Jr. was killed about 3:40 a.m. last March 15. The suit states that Solis encountered the victim near Third and Main streets. After Rodriguez Jr. fled, Solis chased and detained him, then shot the unarmed man four times near Third and Gordon streets, the suit alleges. The victim never threatened Solis and there was "no reasonable basis" for the officer to shoot him, according to the complaint.

During Solis' recent preliminary hearing, one of his roommates testified that the rookie officer was drunk that night and that he told her, "I killed somebody."

Laura Rosales lived with Solis and his female cousin, another Los Angeles Police Department officer, less than two miles away from where Rodriguez was shot.

She said Solis called her and asked her to pick him up at O'Donovan's, a bar on Third Street. Then he called back and told her to meet him on a residential street about six blocks away from the bar, she said. "He got into the car ... he smelled like alcohol. I could tell he was drunk," Rosales testified.
